Question

please give answer .... formula for getting no.of onto function from one set to another

Answer 1

Hey!

What are the number of onto functions from a set A containing m elements to a set B containing nelements.

I found that if m = 4 and n = 2 the number of onto functions is 14.

But is there a way to generalise this using a formula? If yes, what is this formula and how is it derived?

important This is a part of my curriculum and I have an important exam tomorrow. So, I request you to make haste in giving me the solution. I will be very grateful to you.



I Hope It's help you..!!!!
