Suppose that it is known that the number of items produced at a factory per week is

Question:

Suppose that it is known that the number of items produced at a factory per week is a random variable X with mean 50.

(a) What can we say about the probability X ≥ 75?

(b) Suppose that the variance of X is 25. What can we say about P (40 < X < 60)?
