Easy# Obtaining Mean and Variance of a Binomial Random Variable

STATS-XYDXG0

Suppose a person has an $60\%$ chance of getting **rejected** for a date when asking someone out. Note that this probability holds true regardless of who they ask to go on a date.

If they have a plan of asking out $20$ people, what is the mean and variance of the number of dates they can expect to get?
