4

faculty members and

5

students be formed if there are

12

faculty members and

13

students eligible to serve on the committee?

Answer provided by our tutors

C(12, 4)*C(13, 5) = 12!/(4!(14 - 2)!) * 13!/(5!(13 - 5)!) =


= 12!/(4!8!) * 13!/(5!7!) =


= (9*10*11*12)*(8*9*10*11*12*13)/(2*3*4*2*3*4*5) =
