Question 17 Two dice are rolled simultaneously. What is the probability that 6 will come up at least once? (a)1/6 (b) 7/36 (c) 11/36 (d) 13/36 First dice
Total Number of outcomes = 36
Number of outcomes where 6 will come up atleast once = 11
Probability that 6 will come atleast once
= (𝑁𝑢𝑚𝑏𝑒𝑟 𝑜𝑓 𝑜𝑢𝑡𝑐𝑜𝑚𝑒𝑠 𝑤ℎ𝑒𝑟𝑒 6 𝑤𝑖𝑙𝑙 𝑐𝑜𝑚𝑒 𝑎𝑡𝑙𝑒𝑎𝑠𝑡 𝑜𝑛𝑐𝑒)/(𝑇𝑜𝑡𝑎𝑙 𝑛𝑢𝑚𝑏𝑒𝑟 𝑜𝑓 𝑜𝑢𝑡𝑐𝑜𝑚𝑒𝑠)
= 𝟏𝟏/𝟑𝟔
So, correct answer is (c)
