trying for 2 hours lol, like an idiot...

if I'm btn and sb plays 40% of hands and BB plays 40% of hands, what equation shows the % that at least one will play this hand?

Thanks!

There is an easier way to calculate this yourself if you don't know the formulas. This will work when you want to know if at least one, and not exactly one, will play.

Odds that you won't play =60% Odds the opp. won't play =60%
Odds of both happenning are 60% X 60% = 36%

Which you know becomes 64% that either of you will play.
