Overall Records

If you take the average of the Seattle Mariners’ winning percentage and the Los Angeles Angels’ losing percentage, you get the chance that the Mariners win tonight. Then divide by two to find the chance the Mariners win tonight and tomorrow. Then do the same thing for the Oakland Athletics and the Texas Rangers and multiply the two answers together to find the percent chance that the M’s make the playoffs.

(.513+.388)/2= .450 or 45% chance the Mariners win tonight.

.450/2= .225 or 22.5% chance the Mariners win their remaining two games against the Angels.

(.413+.456)/2= .435 or 43.5% chance the A’s lose tonight.

.435/2= .217 or 21.7% chance the A’s lose their remaining two games.

(.225)x(.217)= .0489 or 4.89% chance the Mariners make the playoffs.
