0.9972

Step-by-step explanation:

Given : The proportion of Americans believe that texting while driving should be outlawed : p= 0.97

Sample size : n= 10

Using Binomial distribution , the probability of getting success in x trials is given by:-

, where p is probability of success in each trial and n is sample size.

Then, the probability that at least 8 say that they believe texting while driving should be outlawed will be :_

Hence, the required probability = 0.9972
