this might seem easy but i am easily confused.
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.)
+118680
Here are the stickers XXXXXXXXXX ten of them.
now separate these into 8 groups by puting up dividers. You only need 7 dividers because each person gets the stickers in front of their divider but the last person just gets the ones at the end. Draw it on a peice of paper to see what I mean.
So there are now 10+7 = 17 objects
you need to see how many ways the dividers can be placed in the queue.
17C7 ways ofcourse 17C10 would give the same result.
