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 ''
THanks!
