Airlines, in some cases, overbook flights because past experience has shown that some passengers fail to show up. Let x be the discrete random variable that represent the number of passengers who can't board the plane because there are more passengers than seats.

X 0 1 2 3 4
P(X) 0.802 0.124 0.052 0.009 0.013


What is the mean, variance, and standard deviation?
