Ex15.1, 14 One card is drawn from a well-shuffled deck of 52 cards. Find the probability of getting (i) a king of red colour Total number of cards = 52 Total number of kings of red colour = 2 P (getting a king of red colour) = (๐๐ข๐๐๐๐ ๐๐ ๐๐๐๐ ๐๐๐๐๐ ๐๐ ๐๐๐ ๐๐๐๐๐ข๐)/(๐๐๐ก๐๐ ๐๐ข๐๐๐๐ ๐๐ ๐๐๐๐๐ ) ย = 2/52 = 1/26 Ex15.1, 14 One card is drawn from a well-shuffled deck of 52 cards. Find the probability of getting (ii) a face card Total number of cards = 52 Face cards are King, Queen and Jack Each type has 4 cards Total number of face cards = 3 ร 4 = 12 P (getting a face card)ย = (๐๐ข๐๐๐๐ ๐๐ ๐๐๐๐ ๐๐๐๐๐ )/(๐๐๐ก๐๐ ๐๐ข๐๐๐๐ ๐๐ ๐๐๐๐๐ ) = 12/52 = 3/13 Ex15.1, 14 One card is drawn from a well-shuffled deck of 52 cards. Find the probability of getting (iii) A red face card Total number of cards = 52 Face cards are King, Queen and Jack Total number Red of face cards = 6 P (getting a red face card)ย = (๐๐ข๐๐๐๐ ๐๐ ๐๐๐ ๐๐๐๐ ๐๐๐๐๐ )/(๐๐๐ก๐๐ ๐๐ข๐๐๐๐ ๐๐ ๐๐๐๐๐ ) ย = 6/52 = 3/26 Ex15.1, 14 One card is drawn from a well-shuffled deck of 52 cards. Find the probability of getting (iv) the jack of hearts Total number of cards = 52 We have 4 Jack cards Total number of Jack of hearts = 1 P (getting a Jack of hearts)ย = (๐๐ข๐๐๐๐ ๐๐ ๐ฝ๐๐๐ ๐๐ โ๐๐๐๐ก๐ ๐๐๐๐๐ )/(๐๐๐ก๐๐ ๐๐ข๐๐๐๐ ๐๐ ๐๐๐๐๐ ) ย = 1/52 Ex15.1, 14 One card is drawn from a well-shuffled deck of 52 cards. Find the probability of getting (v) a spade Total number of cards = 52 We have 4 suits โ spade, club, diamond and hearts. Total number of spade cards = 13 P (getting a spade card)ย ย = (๐๐ข๐๐๐๐ ๐๐ ๐ ๐๐๐๐ ๐๐๐๐๐ )/(๐๐๐ก๐๐ ๐๐ข๐๐๐๐ ๐๐ ๐๐๐๐๐ ) = 13/52 = 1/4 Ex15.1, 14 One card is drawn from a well-shuffled deck of 52 cards. Find the probability of getting (vi) the queen of diamonds Total number of cards = 52 We have 4 queen cards Total number of queen of diamonds = 1 P (getting a queen of diamond)ย ย = (๐๐ข๐๐๐๐ ๐๐ ๐๐ข๐๐๐ ๐๐ ๐๐๐๐๐๐๐๐ )/(๐๐๐ก๐๐ ๐๐ข๐๐๐๐ ๐๐ ๐๐๐๐๐ ) ย = 1/52
