Here's why I didn't do the Wizard's bet (besides not making personal bets):

Rolling 2-2 happens 1/36 times.
The bet offered a pay of 9/1 if I remember correctly.

When one die is known, a second die has a 1/6 chance of showing a 2. But when two dice are thrown, showing 2-2 is a 1/36 event.

There are eleven combinations where a 2 shows on at least one of two dice. Of those eleven combinations only one combination is 2-2 (which is what the 1/11 result shows).

While the chance of a single die showing a 2 is 1/6, the chance of throwing two dice with both showing 2-2 is 1/36. The Wiz was paying 9/1 for a 1/36 event.

The figure 1/11 doesn't apply to throwing two physical dice. It only tells you the total number of combinations with 2-2 showing out of all the combinations of dice showing at least one 2. Even if it did there are still TEN chances of losing a bet that pays 9 if won.

It's just a losing bet for me. Coach should not make this bet with anyone.
