What is

What is the probability that the sum of 9 will fall on a roll of two dice?

Hint: write down all the pairs that can occur as follows:
11 12 13 14 15. .
21 22 23 24. .. .
31 32. ..
. .
. . . .. . 66, count them, it's the variable n

variable m: 36, 63,. .. . write it down and count it and substitute it into the formula

Correct result:

p =  0.1111

Solution:

n=6 6=36 3+6;4+5;5+4;6+3 m=4  p=mn=436=19=0.1111
