Solution

## The correct option is C 34Given, a coin is tossed 3 times. Total possible outcomes = {HHH, HHT, HTT, HTH, THH, TTH, THT, TTT} (where H = Heads, T= Tails) Total no. of possible outcomes = 8 Favourable outcomes (getting at least one head and tail) = {HHT, HTT, HTH, THH, TTH, THT} No. of favorable outcomes = 6 Probability of an event E, P(E)=number of favourable outcomestotal number of outcomes ⇒ P (getting at least one head and tail) = 68 = 34 ∴ The probability of getting at least one head and a tail is 34.
