A baseball player has a batting average of 0.38. What is the probability
that he has exactly 5 hits in his next 7 bats?
~~~~~~~~~~~~~~~~~~~ 

It is a binomial distribution probability problem.

The number of trials n= 7;
the number of successful trials is k= 5.
The probability of the individual success for each trial is p= 0.38.


Use the standard formula

    P = C%5B7%5D%5E5%2Ap%5E5%2A%281-p%29%5E%287-5%29 = 21%2A0.38%5E5%2A%281-0.38%29%5E2 = 0.06396  (rounded).   ANSWER

Solved.
