উত্তর: 1/3

We need to determine the probability that a coin lands on the same side for all 3 tosses of the coin. This means that the 3 - toss outcome will be either H - H - H or T - T - T. P(T - T - T) = 1/2 x 1/2 x 1/2 = 1/8 P(H - H - H) = 1/2 x 1/2 x 1/2 = 1/8 Thus, the probability that the coin lands on the same side each time is 1/8 + 1/8 = 2/8 = 1/4. (ans)
