How To Mathematically Win Every Office Bet

Unlikely you’ll be able to pull this off very often in real life, but a fun read on what is essentially an options strategy for your office bets

Suppose we make a second \$5 bet with person B, but this time instead of predicting it to rain more than two inches, we bet that it will rain less than four. Now, if it rains 4 or more, we lose \$5, and anything less we profit \$5. What’s interesting that occurs here is the regions beyond 2 and 4 have conflicting payouts and losses, so when we lose one bet, we win the other. Then, in the region between, we win both.

This could come in handy when betting on some of the 2020 predictions above.
