Question:

A commuter encounters four traffic lights each day on her way to work. Let X represent the number of these that are red lights. The probability mass function of X is as follows.

3 х P(X = x)|0.1 0.3 0.3 0.2 0.1

What is the probability that in a period of 100 days, the average number of red lights encountered is more than 2 per day?
