In general, to calculate the odds of "x AND y", you multiply the chances of x happening times the chances of y happening.
And the only way to calculate the odds of doing "x OR y" is to calculate the odds of "NOT x AND NOT y," and then subtract from one.
In algebra form: (x or y) = 1 - [(not x) * (not y)]
It works the same way for more than 2 tries. Say I'm flipping a coin three times, and I want to know the odds that it will come up heads at least once. To figure this out, you have to ask, what are the odds that it will NOT come up heads at least once, or in other words what are the odds that it comes up tails every time. The odds of tails on any given flip is of course 1/2. So the odds of getting tails on all 3 flips is 1/2 * 1/2 * 1/2 = 1/8. Therefore, the odds of at least one heads is 1 - 1/8 = 7/8.
OK, enough odds blather.

I'll assume that you're right that your chances of catching on the turn & river are 16/47 and 16/46, respectively.
What you have to do is calculate the possibility that you do NOT catch on either street, and then subtract that from zero.
So you have a 31/47 chance of missing on the turn and a 30/46 chance of missing on the river. Your odds of missing on both streets are therefore 31/47 * 30/46, which can be written as (31*30) / (47*46) => 930 / 2162, which is 43.0157%. Your chance of hitting is therefore about 1 - 0.43, or 0.57, or 57 percent.

Results in white below:
Hero has Qh Kh (flush, king high).
UTG has As Kc (high card, ace).
Outcome: Hero wins $38.50.
For some reason the converter is not showing my re-raise on the flop. I don't know how this works, but the total pot was $63, but I won $38.50...I think.
Do you call the raise preflop w/ KQs? The table was pretty loose and I was in position. I think my flop re-raise was okay, but could have been dangerous. I'm in trouble if he has Axs or a set, but other than that I know I'm ok.
On another note, I'm having problems calculating the odds. Someone please help here. I have 9 hearts, 4 10s, 3 queens. 16/47 and 16/46 on the flop and turn..roughly 2:1 to hit on both streets. How do you take into account both streets...I'm pretty sure I'm AT LEAST even money on the flop if he has a low PP...or AK.
