Given a pack of 52 cards, there are 26 black cards.
In a pack of 52 cards, there are 26 black cards. If A is the event that a black card is drawn, then P(A) = 2652=122652=12
After drawing a black card, there are still 25 left in the pack. Let be be the event of drawing a black in the second draw, then P(B) = 2551
