At a certain intersection, the light for eastbound traffic is red for 15 seconds, yellow for 5 seconds, and green for 30 seconds. What is the probability that the light is red? Using the binomial distribution, what is the probability that out of the next eight eastbound cars that arrive randomly at the light, exactly three will be stopped by a red light? P(red) = .15, P(exactly 3 get stopped) = .97P(red) = .3, P(exactly 3 get stopped) = .8 P(red) = .15, P(exactly 3 get stopped) = .08 P(red) = .3, P (exactly 3 get stopped) = .25
