    There is a 1/4 chance that you will flip over both positive cards because there are 4 possible combinations, positive-positive, positive-negative, negative-negative, and negative-positive. Each combination has one chance out of 4 combinations. Therefor there is a 1/4 chance.

    If you have a deck of cards there is four different options that you could have. 1: red black 2:black red 3: black black 4: red red. If you want black black the probability is 1/4.
