A baseball player has a batting average of 0.32. What is the probability that he has exactly 2 hits in his next 7 at bats?
~~~~~~~~~~~~~~~~~~ 

It is the binomial type probability distribution.


The number of trial n= 7; the probability of the success trial is  0.32,  and the number of success trial k = 2. 


    P = C%5B7%5D%5E2%2A0.32%5E2%2A%281-0.32%29%5E5 = %28%287%2A6%29%2F%281%2A2%29%29%2A0.32%5E2%2A0.68%5E5 = 0.3127 (rounded).     ANSWER
