What is the probability that the product of the two numbers drake rolls is less than 13?

    1    2    3    4    5    6

1| 1    2    3    4    5    6
2| 2    4    6    8   10  12
3| 3    6    9   12  15  18
4| 4    8   12  16  20  24
5| 5    10 15  20  25  30
6| 6   12  18  24  30  36

there are 23 options that are less than 13 and 36 options in total so 23/36 

hope this helps :)
