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. WebSee Probability is nothing but Expected Events / All Possible Events So here if we flip 5 coins then all possible events = 2 * 2 * 2 * 2 * 2 = 2^5 = 32 Expected event is getting exactly two head, if you know how combination works then you may find that event of getting exact 2 heads in 5 flips is nothing but 5C2 = 10 shanna rachel
