Question 5 Two fair coins are tossed. What is the probability of getting at the most one head? (a) 3/4 (b) 1/4 (c) 1/2 (d) 3/8 All outcomes = HH, HT, TH, TT Outcomes with atmost one head = Outcomes with no head + Outcomes with 1 head = TT, TH, HT Now, Probability of getting atmost one head = (𝑁𝑢𝑚𝑏𝑒𝑟 𝑜𝑓 𝑜𝑢𝑡𝑐𝑜𝑚𝑒𝑠 𝑤𝑖𝑡ℎ 𝑎𝑡𝑚𝑜𝑠𝑡 1 ℎ𝑒𝑎𝑑)/(𝑇𝑖𝑡𝑎𝑙 𝑛𝑢𝑚𝑚𝑏𝑒𝑟 𝑜𝑓 𝑜𝑢𝑡𝑐𝑜𝑚𝑒𝑠) = 𝟑/𝟒 So, the correct answer is (a)
