    Hello everyone i'm just double checking my work and im' wanting to make sure this one is correct. The problem is:

    How many one to one functions are there from a set with 3 elements to a set with 5 elements?

    I said, 5 choices for first element
    4 choices for 2nd element
    3 chocies for thrid element, so
    (5)(4)(3) = 60 total ''
