Mark rolls two number cubes. what is the probability that the sum of the two numbers will equal 10?

a 1/15
b 1/136
c 1/12
d 1/9se me with this math question?

Every cube has 6 sides and assuming that each face is numbered 1 to 6, the faces that he has to get when he rolls the cubes for the sum to be 10 should be 4 and 6, 5 and 5 or 6 and 4. The probability for each cube is therefore 1/3 and since the combination is Cube1 AND Cube2 you multiply the probabilities (if it were OR, you'd have to add instead)

so the total probability is 

You just divide and you will find x

The best answer is 2lbs
