A dozen eggs contain 12 eggs. A particular dozen is known to
have 3 cracked eggs. An inspector randomly chooses 4 eggs from this
dozen for inspection. Let X be the number of cracked eggs in the 4
chosen for inspection.
a. Find the probability mass function of X in table form.
b. Find the cumulative distribution function of X in table
form.
c. What is the probability that there is at least 1 cracked egg
chosen by the inspector?
d. What is the probability that there are at most 2 cracked eggs
chosen by the inspector?
e. Find the expected value of X.
f. Find the standard deviation of X.
g. What is the probability that between 0.15 and 2.85 cracked eggs
are chosen by the inspector?
