1. Counting & Probability help

Not sure how to do number 1

#1)In how many different ways can 10 different balls be distributed to 7 identical tubs, if some tubs can be left empty?

#2)In how many different ways can 14 identical balls be distributed to 7 identical boxes, if no box can be left empty?

For number 2 I got C(10 + 7 - 1 , 10)

Any help would be greatly appreciated
