Question 262812: Just want to check and see if I did this right?
The Gallup Poll reported that 52% of Americans used a seat belt the last time they got into a car. If four people are selected at random, find the probability that they all used a seat belt the last time they got into a car.
0.52*0.52*0.52*0.52=7.3 people used the seat belt the last time they got in the car.
