A softball player's batting average is defined as the ratio of hits to at bats. Suppose that a player hasa 0.250 batting average and is very consistent, so that the probability of a hit is the same every timeshe is at bat. During today's game, this player will be at bat exactly three times.(a) What is the probability that she ends up with two hits?(b) What is the probability that she ends up with no hits?(c) What is the probability that she ends up with exactly three hit?(d) What is the probability that she ends up with at most one hit?

given data p(hit) = p = 0.250 sample size, n =3 x = No. of time hits p(x=X) = nxC * px * qn-x…

Answered: A softball player's batting average is…
