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.
