I ve got this simple problem and I can can not find the solution.(adsbygoogle = window.adsbygoogle || []).push({});

Two men play head and tails. Each man flips the coin n times, every time he has head, he should add one point to his score. At the end, they compare the scores, whose score has more points , the man is the winner.

A is the probability of a man lose or win, B is the probability when the two have the same points. Calculate A and B?

Thanks
