When we toss 5 fair coins, which sequence is more likely to happen?
A: Getting 2 heads B: Getting 4 heads
A: 2/5
B: 4/5
So I think B is more likely to happen.
5 nCr 2 = 10 / 2^5 =10 / 32 =31.25 % Probability of getting 2 heads on 5 flips.
5 nCr 4 =5 / 2^5 = 5 / 32 = 15.625% Probability of getting 4 heads on 5 flips.
So, the probability of getting 2 heads is TWICE as likely as getting 4 heads.
