Kelly’s batting average is .30 (they hit 3 out of every 10 pitches). Let’s assume there are 120 pitches thrown in the first 8 games. A) True or False. This is a normal binomial distribution.   B) What is the standard deviation of hits you expect for Kelly to have by the end of the first 8 games?   C) What is the likelihood of them hitting at least 40 pitches by the end of the first 8 games? The answer is in percentage(%).
