If x is 1, 2, or 3 and y is either 2 or 4, then the product xy can have how many different possible values?

A. Three

B. Four

C. Five

D. Six

E. Seven

Here let us put the values of x and y and find different possible values

xy= 1 * 2 = 2

xy= 1 * 4 = 4

xy= 2 * 2 = 4

xy= 2 * 4 = 8

xy= 3 * 2 = 6

xy= 3 * 4 = 12

Hence there are 5 different values, because the value 4 appeared twice
