Question 5 One card is drawn from a well shuffled deck of 52 cards. The probability that it is black queen is (a) 1/26 (b) 1/13 (c) 1/52 (d) 2/13 In a deck of 52 cards, we have 4 Queens out of which 2 are black and 2 are red Therefore Total number of cards = 52 Number of black queen cards = 2 Now, Required probability = (𝑁𝑢𝑚𝑏𝑒𝑟 𝑜𝑓 𝑏𝑙𝑎𝑐𝑘 𝑞𝑢𝑒𝑒𝑛 𝑐𝑎𝑟𝑑𝑠)/(𝑇𝑜𝑡𝑎𝑙 𝑛𝑢𝑚𝑏𝑒𝑟 𝑜𝑓 𝑐𝑎𝑟𝑑𝑠) = 2/52 = 𝟏/𝟐𝟔 Hence, (a) is the correct answer
