Acoin is tossed n times and we count the number of tails m and the number of heads n-m. let the random variable y be the difference between the number of heads and the number of tails in the n tosses of a coin, i. e., y=(n-m)-m. assume p({h})= p. a) what are the possible values of y? b) find the probability of y=0 c) find the probability of y=2k. d) find the probability of y=2k+1. hint: your answers in parts b), c), d) should depend on whether n is even or odd
