Consider a binomial experiment with n = 8 trials where the probability of success on a single trial is

p = 0.35. (Round your answers to three decimal places.)

(a) Find P(r = 0).

(b) Find P(r 1) by using the complement rule.

Consider the probability distribution shown below.

x	0	1	2
P(x)	0.25	0.20	0.55

Compute the expected value of the distribution. Compute the standard deviation of the distribution. (Round your answer to four decimal places.)
