WebE (X) = np Var (X) = npq Example In the above example, what is the expected number of heads thrown? E (X) = np Now in the above example, p = probability of throwing a head = ½ . n = number of throws = 10 Hence expected number of heads = 5. This is what you would expect: if you throw a coin 10 times you would expect 5 heads and 5 tails on average WebExample 1.
