Three coins are tossed. What is the probability of getting at most two tails?  Choose the correct choice from the following answers.
A) 5/6 B) 2/3 C) 7/8 D) 8/7 E) 6/9
Explanation :   Total number of outcomes possible when a coin is tossed = 2 (∵ Head or Tail)   Hence, total number of outcomes possible when 3 coins are tossed, n(S) = 2 × 2 × 2 = 8   E = event of getting at most two Tails = {TTH, THT, HTT, THH, HTH, HHT, HHH}   Hence, n(E) = 7   P(E)=n(E)/n(S)=7/8   Answer:7/8
