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 = = = 0.06396 (rounded). ANSWER
Solved.
