Regina just started softball last month. On average, she is able to hit the ball 20% of the balls pitched. Assume the pitcher throws 10 balls.
A) Let X be the number of hits that Regina gets. As we know, the distribution of X is a binomial probability distribution. What is the number of trials (n), probability of successes (p) and probability of failures (q), respectively?
B) Find the probability that she hits at least 1 of the 10 balls pitched.
