    According to my calculator it is 21...

    I'll tell you a cheat... if you go on google, and type in

    7 choose 5

    it will give you the answer. shhhh, dont tell anyone... lol

    Ashley, u did a permutation problem, not a combination/choose... just put in

    7 nCr 5 in your calculator, and you'll get the answer

    its 42.

    in statistics you do 7! divided by 5! and you get:

    7x6x5x4x3x2x1 = 5040

    and divide that by

    5x4x3x2x1 = 120

    which gives you 42

    hope that helps!
