Your pocket contains a random number N of coins, where N follows the Poisson distribution with parameter d. All the coins are identical and weighted so that the probability of landing on head is p. Call X the random variable giving the number of heads obtained after tossing all the coins. Show that X is distributed as a Poisson random variable with parameter Xp.
