Probability someone holds an Ace

[Megenoita]

I held KK in the SB (many callers already in) and raised. Five called. Flop came A J x rainbow. I bet, 2 called, and 3rd raised. I folded. I thought that when 4 others are in the pot with you, one probably has an Ace. How do I do the math for that?

Another question is what % of the time will I flop a flush draw when I have 2 suited cards?

Thanks,
M

The probability that if you have no A that noone else holds an A with 4 in the pot are 59%. And if you hold 2 suited that a flop will come are 118 to 1.

Good Luck
