Answer:

The fund raising committee can be organized in 3,276 different ways.

Explanation:

The committee can have the following structures:

Accounting majors            Finance majors

        0                                          5

        1                                           4

        2                                          3

C(10,0) x C(8,5) = (10! / 10!) x (8! / 3!5!) = 1 x 56 = 56

C(10,1) x C(8,4) = (10! / 9!1!) x (8! / 4!4!) = 10 x 70 = 700

C(10,2) x C(8,3) = (10! / 8!2!) x (8! / 5!3!) = 45 x 56 = 2,520

total possibilities = 2,520 + 700 + 56 = 3,276
