To begin, there are only two ways to find die values beginning with a 3 that will give a score of greater than 14: (5,6). Moving to a first roll of 4, there are 3 values that will do the same: (4,5,6). A first score of 5 gives four values (3,4,5,6), and a first roll of 6 will give four values, as well (3,4,5,6). This gives a total of 13 out of 36 possibilities that will have a product of greater than 14.
