Question

This probability distribution shows thetypical distribution of pitches thrown to abatter in a given "at-bat" in a baseball game.Pitches12345Frequency1520401510Find the probability that the pitcher willthrow exactly 4 pitches to a batter.p = [?]

Answer 1

P(x=4) = xi/n

xi = 15 (relative frequency)

n = 100 (add all the frequencies)

P(x=4) = 15/100

P(x=4) = 0.15
