Flop containing two specific cards

[davim1]

How do you calculate the odds of flopping two specific cards that are completely live?

You hold j-10c and you wish to determine the probability you flop specifically a QcKc and any other random card x .

We just wish to find a third card and couple it with QcKc .
Order doesn't matter so KcQcx is the same as KcxQc .

Once we have two specific cards , there are 48 unknown cards that we can match KcQc with . 48/50c3=0.00244
