Question 27 Two fair dice are rolled simultaneously. The probability that 5 will come up at least once is (a) 5/36 (b) 11/36 (c) 12/26 (d) 23/36 Total Number of outcomes = 36 Number of outcomes where 5 will come up atleast once = 11 Probability that 5 will come atleast once = (𝑁𝑢𝑚𝑏𝑒𝑟 𝑜𝑓 𝑜𝑢𝑡𝑐𝑜𝑚𝑒𝑠 𝑤ℎ𝑒𝑟𝑒 5 𝑤𝑖𝑙𝑙 𝑐𝑜𝑚𝑒 𝑎𝑡𝑙𝑒𝑎𝑠𝑡 𝑜𝑛𝑐𝑒)/(𝑇𝑜𝑡𝑎𝑙 𝑛𝑢𝑚𝑏𝑒𝑟 𝑜𝑓 𝑜𝑢𝑡𝑐𝑜𝑚𝑒𝑠) = 𝟏𝟏/𝟑𝟔 So, correct answer is (b)
