WebThis can happen in two ways: (i) A wins immediately (probability 1 / 2 or (ii) A tosses a tail, but ultimately wins. If A tossed a tail (probability 1 / 2, then in effect B is now "first" so the probability she does not win is 1 − p. We conclude that p = 1 2 + 1 2 ( … WebSince each coin has 2 possibilities, head or tails, we can do 2*2*2, since there are 3 coins, to find the total number of possibilities.

Therefore, Number of favourable affair = 6 Probability of occurring two heads and two tails =6/16=3/8. Hence, the possibility that there should be two heads and two tails after tossing four coins is 3/8.
