for the second one you have to list out the possibilities....
column A : 3+1+3, 3+2+2 (plug in 3 as the first one anf follow accordingly ....we could have 3+0+4 but the minimum amount you can have is 1); ie 2 ways to distribute the money...with at least one person getting at least 3
Column B : 1+1+5, 1+2+4, 1+3+3, 2+2+3, 3+3+1...ie 5 ways to distribute the money.
Thus : column b is greater
