You roll TWO six-sided die. Find the probability of each of the following scenarios in fractions.
1. P(sum=2)
2. P(sum is less than or equal to 4)
3. P(sum=13)
4. P(product)= 20 (Product means multiply)
5. P(product less than or equal to 12)

2 | (1,1) | 1 |
3 | (1,2),(2,1) | 2 |
4 | (1,3),(2,2),(3,1) | 3 |
5 | (1,4)(2,3),(3,2),(4,1) | 4 |
6 | (1,5),(2,4),(3,3),(4,2),(5,1) | 5 |
7 | (1,6),(2,5),(3,4),(4,3),(5,2),(6,1) | 6 |
8 | (2,6),(3,5),(4,4),(5,3),(6,2) | 5 |
9 | (3,6),(4,5),(5,4),(6,3) | 4 |
10 | (4,6),(5,5),(6,4) | 3 |
11 | (5,6),(6,5) | 2 |
12 | (6,6) | 1 |
