A teaser (or a "two-team teaser") is a type of gambling bet that allows the bettor to combine his bets on two different games. [1] The bettor can adjust the point spreads for the two games, but realizes a lower return on the bets in the event of a win.

If each team wins in proportion to its quality, A's probability of winning would be 1.25 / (1.25 + 0.8), which equals 50 2 / (50 2 + 40 2), the Pythagorean formula. The same relationship is true for any number of runs scored and allowed, as can be seen by writing the "quality" probability as [50/40] / [ 50/40 + 40/50], and clearing fractions .
