Team A is going to play against Team B. The only pitcher of Team B can throw about a 100 mile an hour fastball, but he is not good at?controlling it. Therefore the members of Team A are going to try to get four balls without hitting a ball. As a result of this strategy each batsman will get either four balls or a strike out. We are going to calculate the probability of Team A getting a strike out, scoring a run in an inning, scoring several runs in a game.
The problem looks very simple, but calculation is not easy.
