A baseball team's pitching staff has 5 left-handed and 8 right-handed pitchers. If 2 pitchers are randomly chosen to warm up, what is the probability that at least one of them is right-handed?
---------
P(at least one right-handed) = 1 - P(2 left-handed) = 1 - 5C2/13C2
---
= 1 - 10/78
------
= 0.8718
