A pair of coins are tossed simultaneously Each coin has probability p to be heads This pair of cons are tossed n times. Suppose that you win $1 for each toss where the outcomes of the two coins are different, and lose $1 for each toss where the outcomes of the two coins are the same. Let Y = The total amount of gain (wins - losses). The expectation E(Y) is expressed in terms of p and n as follows Onp(1-2) 2p(1-0) Anp(1-P) - np/2
