Answer: 1/8 or 0.125 or 12.5%
There are a total of 9 players on the baseball team. Assuming that Rick is the one batting currently, there would be 8 remaining players, including Devon.
We need to find the probability that Devon, which is one of the 8 remaining players, will bat right after Rick.
Since Devon is 1 out of 8 players, the probability is going to be 1/8 or 0.125 or 12.5%
