Question

A group of people were asked if they had run a red light in the last year. 227 responded "yes", and 455 responded "no".

Find the probability that if a person is chosen at random, they have run a red light in the last year.

Give your answer as a fraction or decimal accurate to at least 3 decimal places

Answer 1

Answer #1

P(If a person is chosen at random, they have run a red light in the last year)

= 227 / (227 + 455)

= 227 / 682

= 0.333
