Question

A group of people were asked if they had run a red light in the last year. 456 responded "yes", and 304 responded "no". Find the probability that if a person is chosen at random, they have run a red light in the last year.

Answer 1

The probability that if a person is chosen at random has run to red light in the last year is 60%.

Explanation:

Since a group of people were asked if they had run a red light in the last year, and 456 responded "yes", and 304 responded "no", to find the probability that if a person is chosen at random, they have run a red light in the last year, the following calculation must be performed:

456 + 304 = 760

760 = 100

456 = X

456 x 100/760 = X

45600/760 = X

60 = X

Therefore, the probability that if a person is chosen at random has run to red light in the last year is 60%.
