Among 39 - to 44-year-olds, 35 % say they have called a talk show while under the influence of peer pressure. Suppose seven 39 to 44 -year-olds

are selected at random.

(a) What is the probability that at least one has not called a talk show while under the influence of peer pressure

(b) What is the probability that at least one has called nbsp a talk show while under the influence of peer pressure ?

(a) The probability that at least one has not called a talk show

while under the influence of peer pressure is?

.

(Round to four decimal places as needed.)

(b) The probability that at least one of the seven randomly selected adults has called a talk show while under the influence of peer pressure is?

(Round to four decimal places as needed.)

if 35% or 0.35 say no, to compute the probability that at least one of 7 called a talk show while under the influence of peer pressure is (1-0.35) ^7 and subtract it from. This is the same as at least 1 has called a talk show while under the influence of peer pressure

1 - (1 - 0.35) ^7 = 0.95
