I have a query over the schools explanation of pots odds. The bit i'm confused over is the following:

Example with the nut flush draw:

You have the nut flush draw (nine outs) on the flop and the pot is \$4. Your opponent bets \$1. There is now \$5 in the pot (\$4 + \$1), and it is \$1 to call. The pot odds are therefore 5:1.

According to the chart above, your odds are 4:1 to hit your flush draw. The pot odds are higher. You should therefore call.

You can see why this call is correct by looking at the long-term picture. If you make this call four times, mathematics says that you will hit your draw once. That means you will win \$5 for every \$4 (4 * \$1) you invest. That is good business.

My query is this...4:1 odds of hitting your draw means that for every 5 plays, you will hit once. (4 i miss, 1 i hit i.e. 4 to 1). So surely the correct explanation for this should read...

If you make this call 5 times, you will win \$6 for every \$5 dollars you invest.

(\$6 dollars is the \$5 dollars in the pot, plus your \$1 investment)

I'd like the schools opinion on this too..

Willy.
