On a typical weekday, the demand for hamburgers is normally distributed with a mean of 450 and standard deviation of 80 and the demand for chicken sandwiches is normally distributed with a mean of 120 and standard deviation of 30.

Let H = hamburger and C = chicken

P(H > 400) = 0.0635

P(C > 150) = 0.0048

P(Both) = 0.0635 x 0.0048 = 0.0003
