A baseball player has a batting average of 0.375. What is the probability that he has exactly 3 hits in his next 7 at bats?

Answer 1

Use binomial probability formula

P(x successes in n tries) = n! p^x (1-p)^ (n-x)

---------

x! (n-x)!

where p = probability of success

here p = 0.375, n = 7 and x = 3.

substitute into formula to compute probability
