Flopping top FH against quads

[timex]

There are 46 cards left, and one must be on of you're two tens, and the other two must be either 2 9's or 2 7's. Lets say 2 7's come, there are 12 possibilities for how the cards could fall, because 3 cards can be arrange in 6 ways and either ten could be in use, so 12/ 46 *45*44. Since either 7's or 9's could fall it is 24/46*45*44 = 1 /23*15*11 = 1 /3795 I think, so about 0.025%. I can't answer Q 2), I'm more of a $5 SNG player [img]/images/graemlins/blush.gif[/img]
