Suppose you wanted to test your ESP using an ordinary deck of 52 cards, which has 26 black and 26 red cards. You have a friend shuffle the deck and draw cards at random, replacing the card and reshuffling after each guess. You attempt to guess the color of each card.

What is the probability that you guess the color correctly by chance?
