In the United States, 43% of people wear a seat belt while driving. If two people are chosen at random, what is the probability that both of them wear a seat belt?

(0.43)^2 = 0.185 = 18.5%

43c2/100c2 = 0.182

To find the probability that both people wear seat belts, we need to multiply the probability of the first person wearing a seat belt by the probability of the second person also wearing a seat belt.

Given that 43% of people wear a seat belt while driving in the United States, the probability of the first person wearing a seat belt is 43% or 0.43.

Now, since the two events are independent (the probability of the second person wearing a seat belt is not affected by the first person's action), we can use this same probability of 0.43 for the second person.

To calculate the probability of both people wearing a seat belt, we multiply the individual probabilities together:

P(Both people wearing seat belts) = P(First person wearing seat belt) * P(Second person wearing seat belt)
= 0.43 * 0.43

= 0.1849

Therefore, the probability that both people chosen at random wear a seat belt is approximately 0.1849, or 18.49%.
