Calculating pot odds.

[wdeadwyler]

I am sure this has been posted a million times before, but I am hoping someone will take the time to explain to me. I am pretty good at math and always feel I have needlessly struggled to calcutate my pot odds. I have all the ratios and percentages pretty much memorized, but at this point in my poker career I want to know how to make exact calculations.

So to calculate odds to hit on next card, its just outs over remaining cards right? So if I flop a four flush, then I am 9/47 to hit on the turn? And finally, to compute with two cards to come its Pof hitting on turn +prob of not hitting on turn*prob of hitting on river. Is this correct?
