There are 50 choose 3 possible flops for each of those holdings. Depending on the holding, there will be 1,2,3,or 4 ways to make a straight flop, so
1, 2, 3 or 4 in 19600 respectively.

There are 4^3 - 4 ways to make each of the 1,2,3 or 4 straights. Besides, he was asking about straight draws. See this post (http://forumserver.twoplustwo.com/showthreaded.php?Cat=&amp;Number=2948434&amp;page=&amp;view=&amp;s b=5&amp;o=&amp;vc=1) to find the answer of 9.6% for 8-out straight draws with JTs-65s, and this post (http://forumserver.twoplustwo.com/showthreaded.php?Cat=&amp;Number=2327858&amp;page=&amp;view=&amp;s b=5&amp;o=&amp;vc=1) for other connectors.

Wow, what a brain fart. For some stupid reason I thought he was asking about straight flushes.
