Let the random variables X1 and X2 denote the length and width of a manufactured part. Assume that X1 is normal with E(X1 ) = 2 and standard deviation 0.1 cm. Also assume that X2 is normal with E(X2 ) = 5 cm and standard deviation 0.2 cm. Also assume that X1 and X2 are independent. What is the probability that the perimeter exceeds 14.5 cm?

The distribution of the time until change (in days) of a Web site is approximated in the following table. Days until Changes Probability 1.5 0.05 3.0 0.25 4.5 0.35 5.0 0.20 7.0 0.15   Calculate the mean for X.

Suppose that X is the number of cars per minute that pass through a certain intersection, and that X has the Poisson distribution. If the mean of X is equal to 9 cars, what is the variance of X?
