Q: A completely unprepared student is given a true/false type of test which contains 10 questions. What is the probability that the student will, by selecting the answers at random, get all answers right?
It is later decided that a pass will be awarded or 8 correct answers. What is the probability of the student passing the test?
Answer:
For first part, using X~Bin (10, 0.5)
P(X=10) = 10C0 x 0.5^10 = 0.0009766
For the second part,
P(X ≥ 8) = 1 - P(X ≤ 7) = 1 - 0.9453 = 0.0547
Conclusion: There is only a 0.09766% chance of getting full marks and a 5.47% chance of passing.
Moral of the story: Even if it kills you Esther, please study Physics before the test date. =.=
And the same goes for the rest. Guessing game never helps. GOOD LUCK FOR TOMORROW!
"I wish I had the power to time travel, like Masi Oka..Then I can stop time just before exam ends, look over people's answers..."
"I wish I had the power to time travel too, so that I can multiply time itself so that I can have more time to study..."
"If I could travel through time, I would go back and get some brain juice from Einstein"
"Haha. NO actually, I've thought of something better. I would go back in time, find some way to kill Einstein so that there will be no theory of relativity and I won't have to be stuck studying them and being confused about them. LOL"
"Oh no, but then without his theory, the world would be topsy turvy with unexplainable events occuring around us"
"But his theory did not bring very good events either. Look what it did to Hiroshima and Nagasaki."
"But, if that did not happened, WW2 might not have ended until now and we won't be sitting here having this conversation peacefully"

EVERYTHING HAPPENS FOR A REASON
I have nothing against Physics. I just need more time. I know I am going to be dead meat next week.
[Even when all hope is gone, move along, move along like I know you would do]
I woke up when my alarm rang at a rather unusual time. I picked up my phone and I saw the reminder on the screen: OMG AAR!. Lol. I still have no idea why I needed a reminder for that. For such a FANTASTIC concert.
The mornings were spent on usual exam revisions for Biology and the thought of me being at the concert hasn't really sink in. It felt exactly like a typical Sunday except the fact that the plumber came. LOL.
I packed the necessary things for the event and Nic's dad picked me up from the station. We stopped by at McD drivethru for tea-dinner since we know there won't be time for that later. We arrived at Bukit Jalil at about 4 and naturally "blend into the line". The sardin packed condition caused by Malaysian kiasu-ism started earlier than I thought, where people were pushing and squeezing over a closed gate. -.- It was hot and stuffy and everybody was angry at each other. But I was kinda expecting this condition and we all had one tune in our head at that moment-MOVE ALONG. Oh my..WHAT WE DID FOR AAR. Lol
We finally braved through the mess and got a pretty good spot. The concert only really started close to 8 with performances from a few local bands. Disagree performed a few songs but "Crumbs" was the only one I was familiar with. The night continued with a mindblowing performance from Pop Shuvit which started with "Old School Rocka" that send the crowd jumping. One Bucks Short performed next and again I was not familiar with their songs but I rocked on along them.
Then the moment everyone was waiting for came although AAR took almost an hour to prepare the stage. We patiently waited although some gave up waiting which was good for us because we were getting closer to the stage. "Move Along"..that is all that matters at that moment.
Finally, Chris of AAR started on the drums for "Move Along" and the crowd was ESTATIC!. We were screaming and jumping and singing along the song they performed. Tyson wore a Native American headband as part of a Halloween dress up. But what truly caught my attention was Nick on the guitar. He is so cool and versatile on the guitar although we only managed to catch a glimpse of him every now and then because he was on the far left of the stage when we were at the right part of it. But I thought HE WAS SO GOOD! I practically yelled " I LOVE YOU NICK" more than 10 times! The awesome sound of the instruments playing together got me literally jumping like mad! XD We were euphoric and our minds were packed with endorphins and adrenaline throughout the entire concert!
The slight dristle did not dampen our spirits too and although we were soaked in sweat and rainwater, the crowd cheered like mad the entire time AAR was performing. Their performances were amazing and they were so HILARIOUS especially Tyson. My mind and eyes were locked on the stage the entire time. For me, it felt like time stopped and there was nowhere else I would rather be at that time. Plus, given the recent stressful thoughts I have been harbouring lately due to exams, last night was really a night to wind down and just let loose of all those thoughts and feelings. I truly had an immense amount of fun.
I was not even exhausted after I came home because I could not get my mind of the concert. Thus, when I wake up this morning, I needed to blog this entry before the memory slowly fades away. But given the fantastic entertainment they provided, this memory will linger around for a very long time.
It was too bad that my camera was gone and I could only take a few blurr pictures of the band. I could not get the T-shirt too as I was not a Digi user. Thus, the few memories from the concert would be my squashed up entry ticket and most importantly, to be able to see, experience and feel the music from the band I love so much.
Now, hard reality strikes back on me. I have a Chem written practical test tomorrow. My feet hurts, I might be losing my voice but I still feel euphoric. XD
This week has been pretty crazy with loads of exams until there was a point where I had to switch my mind from leptons and cyclotrons to benzoic acid and hexaaquacopper ions under one minute. That happened because I had no break at all between Physics and Chem class.
I anticipate next week to be even crazier. Thank goodness for study leaves. And thank goodness for TOMORROW! XD
*Scream loudly*- I AM AN AARMY! XD
Z-OMG! OMG!
The video is out! Adam Lambert's new song "Time for Miracles" is on YouTube. It will also be the theme song for the upcoming movie "2012". As usual, it is AMAZING. I mean what else can I say, we are talking about Adam Lambert here XD. Powerful voice especially at the 2nd half of the song.
His new album "For Your Entertainment" release date has also be announced. But I suspected that 23 November is just for the States. Well that's fine with me but the moment that album reaches here, I will stay true to my word and purchase it immediately. Hee hee. XD
[Instead of abstaining from the blogosphere, I realised that I have been blogging a lot more frequent lately. LOL.]

I planned to wait in front of the computer at 8.55am to check the results. I told myself that as far as I can run from it, I can't possibly hide from it forever.
Did I tell you that I hardly do what I planned? =P
When Sam said she wanted to use her computer to watch Supernatural at 8.45am, I did not stop her well because it is HER computer (lol) and I myself was afraid to check. The next 45 minutes or so was spent drooling over Jared Padelecki's new hairstyle and his usual sexy voice. I actually forgot that it was time to check my results until Sangeetha called, informing Sam her results.
Then, I remembered and I began to feel nervous. It is true that there is nothing much I can do about it. People would probably tell "Oh, don't go crying or worrying over spilled milk" but it is human nature to feel nervous about these things especially where your university admission is concerned.
But I knew I had to face reality. So I log on and type my details carefully, there was a slight problem because I needed to include a dash in my IC no. and my results were finally displayed in front of me.
BAND 8.
=D=D=D=D=D=D=D=D=D=D LOL
In order to quell the paranoia in me of mistyping my information, I searched for my results 3 times.=P Nothing changed. I really got BAND 8!!!!!=D=D=D=D. I am feeling so happy and relieved. =D Congrats to Hui Na and Nisha too! XD
Oh my, Nisha, this REALLY deserves an ice cream! XD
Does "charm" quark brings you good or bad luck? XD
Hmm..an anti-strange quark...does it mean that it's normal?=P
Did you know "strangeness" can be quantified? A strange quark has a strangness of 1. NO KIDDING
What are neutrinos and why do they keep tagging along with leptons during reactions?
It is 0523 hours. Not exactly the best time to be unravelling this topic. But then again, maybe t is since I can even hear the sound of silence. Hee hee.
IELTS results in less than 4 hours! (That is if punctuality is one of their qualities ;))
