A firm sells two products, A and B. Both products have normally distributed demand. Both have the same mean and standard deviation. Consequently, they have the same coefficient of variation, which happens to be 0.5. If we were to measure the coefficient of variation (CV) of total demand (the sum of demands for products A and B), we would find that the CV of the total demand:
a) Equals 0.5
b) Is greater than 0.5
c) Is less than 0.5
d) Cannot be determined from the given information
