Mike is a major league pitcher. He pitches like a robot, that is he pitches the same way to each batter. There is a .56 probability that the first ball he pitches to a batter is a strike. (first-pitch strike). This is independent from batter to batter. Let X equal the number of first-pitch strikes Mike throws in a game where he pitches to 15 batters. Let Y equal the number of batters he pitches to until he throws his 2nd first-pitch strike. (could be more than 15)
a. What is the probability X=13?
b. What is the standard deviation of X?
c. What is the probability that X > 10?
d. What is the probability that X ≥ 12?
e. What is the probability that Y = 3?
f. What is the probability that Y = 2?

One of the fastest recorded pitches in major-league baseball,
thrown by Tim Lincecum in 2009, was clocked at 101.0 mi/h. If a
pitch were thrown horizontally with this velocity, how far would
the ball fall vertically by the time it reached home plate, 60.5 ft

Think about Major League Baseball! The
owners of the major league teams are arguing that they may have to
shut the season down unless the players agree to a significant
salary cut. If the players agree, the owners will be able to play
games this season.
Explain loss-minimization and shut
down cases for perfectly competitive firms. Explain why baseball
owners may have to resort to a shut-down case and why they may be
able to use a loss-minimization case.
