Question

On your next turn in the game, you are 8 spaces away from climbing a ladder, which will allow you to pass both Alex and Jeff. What is the probability of landing on the ladder if you roll 2 number cubes?

Answer 1

Are these number cubes the traditional dice, marked 1-6 on each side?
If so, we can find the probability of rolling *exactly* 8 with two dice rolls.
I'll give an example. Consider if we were trying to roll 7, instead of 8. How could we possibly do that?
In that case, we could roll (1,6) (6,1) (2,5) (5,2) (3,4) or (4,3). That's 6 possible combinations that total to 7. We also know that there are 36 combinations in all that are possible when rolling 2 six-sided die. So, that's how we'd figure out that the probability of rolling *7* would be 6/36, which is also equal to 1/6.
Can you apply this method to find the probability of rolling 8?
Start by listing out the possible combinations that total to 8. You should be fine from there.
