Probability
" Probability " represents the chances of something that will happen. In M'sia education system, we learn probability during secondary school in the maths / statistic (I dun rilly rmb =P). Today I come across with some tricky probability questions: In a game show, u r given choices of 3 doors. There is only a door with a car behind it whereby the rest has nothing. Lets say if u choose door #1. The host of the show will then open a door that has nothing behind it (eg. #3). After that u r given a chance to switch ur choice between door #1 and #2. What is the probability of getting the car between 2 choices : switch or no switch? Assume that the host will always open one of the empty door... The correct answer is 2/3 if u change ur selection to door #2 and 1/3 if u remain ur initial choice. Do u agree with this answer? Try figure out the reason behind it ... =P.. At first I thought it should be 1/2 chance for both cases... however if u try to analyze the possible of combinat...
