We typically write this probability in one of two ways: P(A or B) – Written form; P(A∪B) – Notation form; The way we calculate this probability depends on whether or not events A and B are mutually ...
WebSolution. Total number of events = total number of cards = 52 52. Probability of drawing a queen = 4/52 = 1/13. Now, the total number of cards = 51 51. Probability of drawing a king = 4/51. So, the probability of drawing a king and a queen consecutively, without replacement = 1/13 * 4/51 = 4/ 663. ∴ ∴ Probability is 4/663.
