Question

in the united states, 73% of people wear a seat belt while driving. if two people are chosen at random, what is the probability both people wear belts

Answer 1

They would have a medium-highish chance of them wearing seat belts

Explanation:

This is because 73% is a bit ways above 50%, so there would be a high-ish chance of them wearing it. Hope this helps.

Answer 2

0.53

Explanation:

This is a case of joint probability. The probability that the first person chosen is wearing a belt is 0.73; the prob. that the second person chosen is wearing a belt is 0.73. The joint probability, that is, the probability that both of the two people chosen at random are wearing their belts, is 0.73^2, or 0.53. This assumes that the event that a given person is wearing his belt is completely independent of the event that some other person is also.
