Explanation / Answer

Suppose we have cards A, B, and C. All possible pair of these cards are: ( A, B) , (A ,C) and ( B, C).

Assume that card A has reach its limit, so probability of pick two cards are good is 1/3.

OR

Simillarly, if card B reach its balance limit then probability of pick two cards are good is 1/3.

OR

Simillarly, if card C reach its balance limit then probability of pick two cards are good is 1/3.
