A-3-5

I decided to figure out the probability of any one of three cards falling on the flop. I wanted to figure this probability out after I won $100 by betting that an Ace, a Three or a Five would be flipped up. I knew the odds were in my favor, but I didn't know by how much.

Here's how I think you do the calculation:

40/52 * 39/51 * 38/50 = The probability that an Ace, a Three or a Five will NOT be flopped. That comes to 59280/132600, or 0.447.

So the odds that an Ace, a Three or a Five will be flopped is 55.3 percent (1 - 0.447). I had guess that it would be somewhere around 60 percent, but the odds weren't quite that high in my favor.

If my math is wrong, please let me know.
