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.)

To Solve this question, we can use Stars and Bars.

In this one, we will be putting 7 bars down, and there are 10 "bars"

There are 11 ways to put the first "bar" down

There are 12 ways to put the second "bar" down

There are 13 ways to put the third "bar" down.

This pattern continues, so the total will be

11*12*13*14*15*16*17= 98017920 ways

 

Somebody and/or Question-Asker check this, because I'm not quite good at this type of math really.
