KQs before the flop--help figuring probabilities

[beekeeper]

I am cross-posting this in the beginner's forum too b/c it may be too rudimentary for this forum.

I folded KdQd from the big blind three-handed recently, mostly trying to finish in the money when we were 2 small stacks against one giant stack, and the button and SB went all in. Payout structure for the tournament was 3rd place gets his buy-in back, 2nd and 1st pay 40:60 respectively from what remains (20 person tournament).

From my read on the button and the small blind I thought I would be up against an Ace and a pocket pair. I knew I had the chance to triple up, but I also thought that I would have to pair one of my cards and avoid an Ace to have a chance.

Can anyone help me figure out the probabilities of this?

Also, how do I factor in my flush draw?

If this question is not appropriate for this forum, let me know. Thanks.
