Mark noticed that the probability that a certain player hits a
home run in a single game is 0.175. Mark is interested in the
variability of the number of home runs if this player plays 200
games. If Mark uses the normal approximation of the binomial
distribution to model the number of home runs, what is the standard
deviation for a total of 200 games? Answer choices are rounded to
the hundredths place.

A baseball player, Mickey, who bats 310 (or .310) gets an
average of 3.1 hits in ten at bats. We will assume that each time
Mickey bats he has a 0.31 probability of getting a hit. This means
Mickeys at bats are independent from one another. If we also assume
Mickey bats 5 times during a game and that x= the number of hits
that Mickey gets then the following probability mass function,
p(x), and cumulative distribution function F(x) are...

Let's say the probability that a Major league baseball player
hits a homerun is 0.099. What is the probability that he hits
exactly 40 homeruns in his next 500 at bats?

A baseball player hits a home run, and the baseball just clear a
wall 27 m located 144 m from the home plate. The ball is hit at an
angle of 38 degrees to the horizontal, and air resistance is
negligible. Assume the ball is hit at a height of 1.0 m above the
ground. What is the initial speed of the ball? (use g = 10
m/s2).
How much time does it take for the ball to reach the...

The probability that Babe Ruth hits a home run on any given
at-bat is 0.12, and each at-bat is independent.
Part A: What is the probability that the next
home run will be on his fifth at-bat?
Part B: What is the expected number of at-bats
until the next home run?
