Ok! Hello this is HyperBrain.
Let d1 be the first dice and d2 be the second dice.

As we all know, a die has 6 numbers (1,2,3,4,5,6)

So D1 can produce 1,2,3,4,5, or a 6.
Same as for D2
So, here are the possible combinations

Now, i will highlight the ones that have the sum of 9.


Now, the formula! tandandan!
PRObability=(no. of highlighted cells)/(total no. of cells)

=4/36=1/9

Power up,
HyperBrain!
