odds of having a flop in poker with at least 10 or higher
I was wondering how often low flops (flops with all cards less than 9) happen. Or we could do the opposite, odds of having a flop in poker with at least an A, K, Q, J, or 10. I was wondering how to do this properly. Let's say the hand I'm holding is random (negligable) so the amount of cards in the deck is to be 52. So 3 flop cards out of 52.
It would help me enormously because if I knew how to do this, I could expand further and figure out other problems.
