Statistics

Question: An urn contains an infinite number of coins that are either two-headed or two-tailed. The proportion of each kind is the same. If we choose M coins at random, explain why the probability of obtaining k heads is given by (3.28) with p = 1/2. Also, how does this experiment compare to the tossing of a fair coin M times?
