A card is drawn at random form a well-shuffled deck of playing cards. Find the probability that the card drawn is either a king or a queen.
Total number of all possible outcomes= 52
Total number of kings = 4
Total number of queens = 4
Let E be the event of getting either a king or a queen.
Then, the favourable outcomes = 4 + 4 = 8
∴ P( getting a king or a queen) = P (E) = `8/52 = 2/13`
