(See exercise 42 on page 253 in your textbook for similar problem.) Find the probability that at least 13 Americans are not satisfied with the way things are going

Explanation / Answer

The probabilty that at least 13 Americans are not satisfied with the way this are going is 0.8697

since

P(at least 13 Americans are not satisfied with the way this are going )

= 1 - P(at least 13 Americans are satisfied with the way this are going )

= 1 - [ 1 - P(at most 12 Americans are satisfied with the way this are going )]

= P(at most 12 Americans are satisfied with the way this are going )

= 0.8697
