You flip a fair coin.  What is the probability that you get 2 heads and 3 tails?

Obviously....  5 times    Right?

There are 32 possibilities    such as    T T T T T     T T T T H   T T T H T     etc

I believe only 10 will have 2 heads and three tails

 

10/32   =  5/16

5! / [2! * 3!]=10
10 / 2^5 =5 / 16 =31.25%
