Answer #1

X: number of times Larry David gets called "bald" in a Curb Your Enthusiasm episode

X follows a Poisson distribution with mean = 3; Probability mass function of X is given by

Probability that Larry David gets called "bald" 'x' times in an episode = P(X=x)

probability that Larry David gets called bald '0' times in an episode = P(X=0)

probability that Larry David gets called bald 0 times in an episode
