A tosses 2 coines while B tosses 3. The probability that B obtains more number of heads is

Each of two persons tosses three fair coins. The probability that they obtain the same number of heads is

Each of A and B tosses two coins. What is the probability that they get equal number of heads ?

Two coins are tossed five times. The probability that an odd number of heads are obtained, is

If A and B toss 3 coins each, The probability that both get equal number of heads is

Each of the persons A and B independently tosses three fair coins. The probability that both of them get the same number of heads is :
