a) What is the probability that the host of the late night show is bleeped more than 3 times?
P(X>3 bleeps) =
(Round to two decimal places as needed.)
b) What is the probability that the host of the late night show is bleeped 5 or less times?
P(Xless than or equals≤5
bleeps) =
(Round to two decimal places as needed.)
c) Compute the mean number of bleeps per show by this late night host.
μ=
(Round to two decimal places as needed.)
d) Compute the standard deviation.
