Question:In baseball, a batting average is the probability that a player will get a hit during his next at bat. Hank started a game with a 40% chance of getting a hit. After the game, his percentage of hits was only 25%. What is the fewest number of at-bats he could have had in that game?
Answers:
Well, the smallest fraction that you can get a 0.400 batting average is 2/5. If, in the next game Hank goes 0/3, he'll have 2/8, which is a 0.250 batting average.
The larger the fraction, the more at-bats he would need in one game to make that significant a jump. So the answer is 3.
I'm not sure, but I think it is 15...
