Re: what formula?

yes, if we use football for example.

two teams play and it can be either a win, draw or loss.

if there is 10 games in total and you wanted to cover every outcome then how many out comes would you need to cover?

does that make more sense?

59,049 seems a little high, you may be correct though.

Hi 7point13;

If your states  that 2 teams play 10 games with 3 possible outcomes then soroban is correct.

3 * 3 * 3 * 3 * 3 * 3 * 3 * 3 * 3 * 3 * 3 = 3^10 = 59 049 outcomes
