Question

Finding Probabilities of Compound Events
A table containing 36 possible outcomes. There are 3 desired outcomes.

What is the probabibility of rolling a sum of 10 when rolling two number cubes?
StartFraction 1 over 12 EndFraction
StartFraction 1 over 9 EndFraction
One-third
StartFraction 5 over 12 EndFraction

Answer 1

There are 36 equally likely outcomes for two dice and 3 give a sum of 10: (4,6), (5,5), (6,4). So the probability = 3/36 = 1/12.
