(a) what is the probability that at least one has not called a talk showcalled a talk show while under the influence of peer pressurepeer pressure? (b) what is the probability that at least one has called nbspcalled a talk showa talk show while under the influence of peer pressurepeer pressure?

0.8997, 0.9999

Step-by-step explanation:

Given that among 46- to 51-year-olds, 28% say they have called a talk show while under the influence of peer pressure.

i.e. X no of people who say they have called a talk show while under the influence of peer pressure is binomial with p = 0.28

Each person is independent of the other and there are only two outcomes

n =7
