Question: Problem 17)

The probability that a theater patron will request seating on the main floor is 0.35. A random sample of 6 patrons call for tickets. Let r be the number who request main-floor seating.

a) Find P(r) for r=0,1,2,3,4,5, and 6

b) Make a histogram for the r probability distribution.

c) What is the expected number out of 6 who will request main-floor seating?

d) Find the standard deviation of r.
