Question 1131636: Suppose a certain traffic light shows a red light for 45 seconds, a green light for 45 seconds, and a yellow light for 5 seconds.
Each day you look at this light at a randomly chosen instant. What is the probability you see a red light five days in a row? (Round your answer to three decimal places.)

The probability to see a red light at a random time moment is 45%2F%2845%2B45%2B5%29 = 45%2F95 = 9%2F19.


The probability to see a red light at 4 randomly selected time moments is %289%2F19%29%5E4.      ANSWER

Solved.
