Question:

Suppose that it is known that the number of items produced in a factory during a week is a random variable with mean 50.

(a) What can be said about the probability that this week’s production will exceed 75?

(b) If the variance of a week’s production is known to equal 25, then what can be said about the probability that this week’s production will be between 40 and 60?
