3-103 A particularly long traffic light on your morning commute is green 15% of the time that you approach it. Assume that each morning represents and independent trial.
- Over 3 mornings, what is the probability that the light is green on exactly one day?
- Over 15 mornings, what is the probability that the light is green on at most 1 day?
- Over 18 mornings, what is the probability that the light is not green on at least one day?
