Suppose that in a certain metropolitan area, seven out of 10 households have cable tv. let x denote the number among six randomly selected households that have cable tv, so x is a binomial random variable with n = 6 and p = 0.7. (round your answers to four decimal places.)
(a) calculate p(3) = p(x = 3).
p(3) =

(b) calculate p(6), the probability that all six selected households have cable tv.
p(6) =

(c) determine p(x ? 5).
p(x ? 5) =
