which has a big chance to make a hand: 3 card badugi, 4 card 2-7 low

Could you re-ask that in a way that humans would understand?

• If you're drawing to 7432, not all of the same suit, any five or six will make a seven. That's a total of eight cards. Similarly, if you're drawing to 7642, not all of the same suit, any trey or five will make a seven, again a total of eight cards.

• When playing badugi, the rough equivalent of an eight out draw in 72TD, would be drawing to make a jack-badugi.

If you want to count any four card badugi as a good hand, you're drawing for one of ten cards.

If you want to count a four card badugi, eight or better, as a good hand, you're drawing for one of five cards.
Suppose, for example, you are dealt
A,5,6,6.
You want any heart except A, 5, or 6 to make a badugi, a total of ten cards.
But only 2,3,4,7, or 8 (a total of five cards) will make you an eight or better badugi.
(You're going to discard the 6, of course).
