52 cards: 52 possible outcomes. P = Specific/All
......
P(H) = 13/52 = 1/4 (There are 13 Hearts in a deck)
..
P(7 AND Club) = 1/52 (only one 7 of clubs in a deck)
..
P(7 0r club) = 4/52 + 13/52 - 1/52 = 16/52 = 4/13
(subtracting the '7' already counted in 4/52)
..
P(J) = 4/52 = 1/13 (4 Jacks in a deck)
..
P(Black card) = 26/52 = 1/2
