The probability that the other face is red is {2/3}. EXPLANATION : There are three equally likely possibilities when a red face is observed: you drew the red-red (RR) card and saw its first side, you drew the RR card and saw its second side, or you drew the red-black (RB) card and saw its red side. In two of these three scenarios (both from the RR card), the other face is also red. The RB card scenario results in a black face on the other side. Thus, two out of the three equally likely possibilities have a red face on the other side.
