Answer:

0.53

Step-by-step 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.

Answer:

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

Step-by-step 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.
