I need to know how to get the number of possible onto functions (as opposed to the number of one-to-one functions) in between sets A and B: A: {1, 2, 3, 4, 5} B: {a, b, c}. Please help if you can.
If A has eight unique elements and B has eight unique elements, how many one-to-one functions would there be? Also, I'd like to know how many there would be if A happened to have less elements than B or if B had less elements than A. Thank you for your time.
