Phone Interview #2 You are playing a game of baseball. There are two outs in the bottom of the ninth, and you are down by one run. You are currently a baserunner on first base. [Obviously, you must score or else the game ends]. A)You are trying to figure out if you should steal second base or not. What kind of information do you need to know to inform this decision? B) Every batter in your lineup has identical odds.They get a single 50% of the time and they strike out 50% of the time. If you are on first base, you cannot score on a single. If you are on second, you are guaranteed to score on a single. You successfully steal 75% of the time. Should you steal? [I may be missing some of the nonsense here, but this is all the relevant information] C) It turns out the pitcher acts a bit differently with a runner on second [regardless of who the batter is] and no other runners on base. Under these circumstances, he is 50% to strike them out, 40% to surrender a walk, and 10% to surrender a hit. How does this change things/ should you steal?
