A game consists of tossing a coin 3 times and noting its outcome. A boy wins the game if all tosses give the same outcome (i.e three heads or three tails) and loses the game otherwise. The probability that the boy loses the game is

Options

  1. A3 4
  2. B1 4
  3. C2 3
  4. D1 3

Correct answer

A. 3 4

Step-by-step solution

Number of sample space =2 2 2=8 Now, favourable outcome = array l HHT, HTH, HTT THH, THT, TTH array So required probability = 6 8 = 3 4
