Re: Odds of hitting Broadway...
Ok, I think I figured out how to do this, can someone tell me if this looks right?
Assume, without loss of generality (since any two non-paired 10+ cards should be as good as any other), I have JT, and my opponent has no 10+ cards (say, a lower pair). I need an ace, a king, and a queen. There are 4 ways to get the ace, out of 50 cards. After that, there are 4 ways to get the king, out of 49, and 4 ways to get the queen, out of 48. And then two cards that can be anything. Then multiply by 5! (= 120) since I don't care about the order. So (4/50) * (4/49) * (4/48) * 120 = 64/117600 * 120 = 0.065. If instead of a lower pair, my opponent had, say, AK, it would be: (3/50) * (3/49) * (4/48) * 120 = 36/117600 * 120 = 0.037. These seem like the right magnitude to me (unlike the numbers I was getting before, that were in the 35% range), am I making any major mistakes here? |
