Suppose that we have a deck of 30 cards. Both sides of the first 10 cards are colored red, both sides of the next 10 cards are colored black, and on the last 10 cards, one side is colored red and the other side black. The 30 cards are shuffled, and the top side of the top card is revealed. If that top side is colored red, what is the probability that the other side of that card is colored black? use formula P( A|B) = P(A and B) / P(B).
