Answer:
Product Rule
Step-by-step explanation:
According to the product rule, the number of possibilities of two independent events happening in sequence, is given by the product of both number of possibilities.
In this case, since there are 17 mathematics majors and 325 computer science majors and they do not overlap, the total number of ways to pick two representatives so that one is of each major is:
n = 17 x 325 = 5,525.
