Twenty-five percent of the customers entering a grocery store between 5 P.M. and 7 P.M. use an express checkout. Consider five randomly selected customers, and let x denote the number among the five who use the express checkout.
(a) What is p(3), that is, P(x = 3)?
(Round the answer to five decimal places.)
p(3) =
(b) What is P(x ≤ 1)? (Round the answer to five
decimal places.)

Zingo's Grocery store claims that customers spend an average of
5 minutes waiting for service at the stores deli counter. A random
sample of 45 customers was timed at the deli counter, and the
average service time was found to be 5.75 minutes. Historically the
standard deviation for waiting time is 1.75 minutes per
customer.

the mean time that customers wait at the deli counter.
