Here's what I am trying to figure out: You have one batter that's average is .200 and another batter that's average is .300. If they bat back-to-back throughout the game, what is the probability (% chance) that one of them will get a hit at any given time between them, taking away all other variables? I am wondering because I was thinking about a Pirates situation the other day and was debating whether they should sacrifice bunt or swing away. I've never tried to figure out the probability combining two players getting a hit before and I'm having difficulty with the math here. FYI, it was Travis Ishikawa and Chris Stewart batting in that order, and I was hoping Clint Hurdle would have had Ishikawa sacrifice bunt in that particular situation. He let Ishikawa swing away and he struck out. I wanted to see if Hurdle made the right decision or not, so I rounded Ishikawa's batting average to .200 and Stewart's to .300 to simplify (that is almost exactly what both of their averages were anyway). Does anybody know how to figure out the exact probability in this scenario?
