If we toss 2 coins simultaneously, the possible outcomes are as follows. (where H = heads, T = tails) . If Coin1 shows Heads and Coin2 shows Heads, let us represent it as (H,H). If Coin1 shows Heads and Coin2 shows Tails, let us represent it as (H,T). Thus, we have the following combinations: (H,H) (T,T), (H,T), (T,H) - exactly 4 possible results.
