There are N cards. The probability that the first card is in the subset is 0.5. The probability that the second card is in the subset is 0.5. ... The probability that the Nth card is in the subset is 0.5.
So if there were 3 cards called A, B, and C, then there are 8 equally likely subsets: ABC, AB, AC, BC, A, B, C, and the empty set.
