Question
Overall, Fary hits the strike-zone with 88% of his pitches (that is, the probability that he hits the strike-zone with any given pitch is .88). (a) One day, he throws 150 pitches. What is the probability that he hits the strike-zone with exactly 134 pitches? (b) Over the course of one week, Fary throws 500 pitches. What is the probability that he hits the strike-zone with 425 or more pitches? Now, every day for eternity Fary throws 50 pitches and records the number with which he hits the strike-zone. (c) Find the mean μ, and the standard deviation o, of the numbers (of pitches with which he hits the strike-zone on different days) that Fary records.
