Question 1153665: The cycle of a traffic light at an intersection of two streets is 35 seconds green, 5 seconds yellow, and 10 seconds red. If you reach the intersection at a random time, what is the probability that the light is red?
This probability is the ratio of the duration of red light (10 seconds) and the full cycle duration of
35 + 5 + 10 = 50 seconds.
So, the probability under the problem's question is P = = = 0.2 = 20%. ANSWER
