On Sunday an Oakland Athletics fan caught two consecutive foul balls. Commentators have opined that the odds against this event were one in a billion or one in a trillion.
At first blush, statistical analysis suggests those odds are wildly overstated. Here's a back of the envelope calculation: with a little over 15,000 in attendance, and assuming that 40 foul balls were hit into the stands during a game, the average fan has a 1 in 375 chance of catching a ball. The chance of getting two balls in the same game is one in 375 squared, about 141,000-to-1. Of course, the probabilities can be adjusted by seat placement--the upper decks in large stadiums get hardly any--but we're still a far cry from one in a billion.
If we layer in another filter, the odds of back-to-back balls landing in the same place must be at least 1 in 10,000. Now we're at 1 in 1.41 billion (141,000 x 10,000). OK, you can cheer now.
Another phenomenon is how much joy one derives from snagging a fly. Every guy is an excited little boy again when he catches a ball that costs about $30.
Female fans show their joy, too. This San Diego fan became an internet celebrity and received several marriage proposals due to her one minute of fame.
