    3003 different groups of 6tops

    Step-by-step explanation:

    Using the combination formula, generally, when selecting r number of objects out of a pool of n numbers, this can be done in nCr number of ways.

    nCr = n! / (n-r) ! r!

    If there are 14 tops I'd like to purchase and I can only afford six, the number of ways I can choose this six at random from the 14tops can be done in 14C6 number of ways.

    14C6 = 14! / (14-6) !6!

    14C6 = 14!/8!6!

    14C6 = 14*13*12*11*10*9*8!/8!*6*5*4*3*2

    14C6 = 14*13*12*11*10*9/6*5*4*3*2

    14C6 = 14*13*12*11/8

    14C6 = 3003ways
