Question 26 A card is drawn from a well shuffled deck of cards. What is the probability that the card drawn is neither a king nor a queen? (a) 11/13 (b) 12/13 (c) 11/26 (d) 11/52
Now,
P(neither king or queen)
= 1 − P(king or queen)
Total Number of Cards = 52
Number of King and Queen cards = 8
Now,
P (getting king or queen) = (𝑁𝑢𝑚𝑏𝑒𝑟 𝑜𝑓 𝑘𝑖𝑛𝑔 𝑜𝑟 𝑞𝑢𝑒𝑒𝑛 𝑐𝑎𝑟𝑑𝑠)/(𝑇𝑜𝑡𝑎𝑙 𝑛𝑢𝑚𝑏𝑒𝑟 𝑜𝑓 𝑐𝑎𝑟𝑑𝑠)
= 8/52
= 𝟐/𝟏𝟑
Therefore,
P(neither king or queen) = 1 − P(king or queen)
= 1 − 2/13
= 𝟏𝟏/𝟏𝟑
So, the correct answer is (a)
