What's the probability that you will take a train in a wrong direction and take the wrong bus at the same time. say twice for taking train in wrong direction, and twice for taking wrong bus in a year. its (2/365)x(2/365). what's the probability that CCA is canceled? say 3/40
What happened today? (2/265)x(2/365)x(3/40)
P( all happening on the same day) = 2.25 E -06
0.000225% chance of happening.

What's the conclusion? I must be extremely unlucky today.

Got this from XN latest blogpost and i decided to calculate how lucky i am today..

Probability of me falling off my bed : 1/730 (its not common for me to fall off =.= once in two years is already exaggerating)
Probability of me having serious stomach ache with vomit feel : 1/365 (i had one the previous year too)
Probability of me having a suspected case of asthma 14/600 (with reference to number of people having asthma in singapore)
P(all happening on the same day = 1/730 x 1/365 x 14/600 = 0.0000087% chance. THERE!

LOL. =/ That my friend. is 85 chances out of 1billion WTH!
