Buzz, can you check my numbers?

Sure, Sam.

Holding AQ42 as an example of any low-low-low-high hand:

The flop contains exactly two low cards that are not A, 2, or 4 AND are not themselves paired 17.6% of the time.

(19*20*16/2)/(48*47*46/6) =
3040/17296 = 0.1758

Looks like we agree on the first one.

The flop contains exactly two low cards, one of which IS an A, 2, or 4, and one of which is not A, 2, or 4 9.9% of the time.

But I get a different answer (19.77%) for the second one. (as shown below):

9*20*19/17296 = 3420/17296 = 0.1977
