Question 1046758: Having trouble with this problem:
On a certain street are three traffic lights. At any given time, the probability that the light is green is 3/10. What is the probability that a person will hit all three lights when they are red if the lights are independent events? Answer by rothauserc(4718) (Show Source):
You can put this solution on YOUR website! The probability that a light is red = 1 - 3/10 = 7/10
:
we multiply independent events
:
probability that the driver hits all three red = 7/10 * 7/10 * 7/10 = 0.343 approx 0.34
