Find the number of ways that Magnus can give out 10 identical stickers to 8 of his friends. (Not everyone has to get a sticker.)
I don't exactly remember how to do these type of problems...
but I believe this is a problem involving combinations....
10 stickers to 8 friends...10*8 = 80 ....so 80 different ways??...
I hope this helps....
Using sticks and stones strategy, you will have 7 sticks and 10 stones, so seventeen different objects. If we have 17 slots, we can first place the 7 sticks in 17c7= \(\boxed{19448}\) ways.
