What is the probability...?

Question

Suppose you are playing a game in which two fair dice are rolled. You need to land on the finish by an exact count or 3 to land on a "roll again" space. What is the probability of landing on the finish or rolling again?

Answer 1

You need to say how far away the finish is. I will assume it is a where a is less than or equal to 12. let c be the number of combinations that result in a.

P(3) = c/36)

P(a)=c/36

P(3 or a) = c/16

Hope this helps
