part A is just simple multiplication
since there are 2 6 sided number cubes there are 36 possible outcomes(6 sides *6 sides)
Part B is a little trickier. First off, you must find how to get seven.
1. 1+6 and 6+1
2. 2+5 and 5+2
3.3+4 and 4+3
therefore there are six combinations
you put that number over the total combos and get 6/36 or 1/6.
Hope this helps!
