A has n+1 coins B has n coins, for upto n coins both have equal probability of getting equal heads,for (n+1)th coin it can be either head or tail with equal probability of 1/2, so the probability that A gets more head than B is 1/2
OR either A throws more head than B,or A throws more tails than B, both having equal probability and are mutually exculscive ,hence ans. is 1/2
