A baseball pitcher gives up a hit on the average of once every third pitch. If 9 pitches are thrown, what is the probability in each case below? Success p = P( Success ) = P( Allowing a hit ): Hits Pitches Probability Pitches: 9 1 3 0.33333333 What is the probabilty that exactly 3 pitches result in hits? Hits: ps= (1 - p)6 = P(x = 3) = + What is the probabilty that no pitches result in hits? Hits: 0 po = (1 - p)' = P(x = 0) = What is the probabilty that exactly 7 pitches result in hits? Hits: p = (1 -p)2 = P(x = 8) = What is the probabilty that exactly 8 pitches result in hits? Hits 8 p = (1 -p)' = P(x = 8) = What is the probabilty that exactly 9 pitches result in hits? Hits 9 (1 - p) = P(x = 8) = What is the probabilty that at least 7 pitches result in hits? P(at least 7) =
