A dress-shop owner has 8 new dresses that she wants to display in the window. If the display window has 5 mannequins, in how many ways can she dress them up?

Sagot :

This question uses combination.

So formula is (8!)/(8-5)!5!

40320/(3!)120

40320/720 = 56

You have 56 combinations of how to dress the mannequin
