Question

Suppose two coins are tossed. Let Y be the random variable representing the number of tails occur. Find the values of the random variable.

Answer 1

Let's H denote for Heads and T denote for Tails.

Thus all the possible outcomes when tossing 2 coins:

{TT, TH, HH, HT}

Y represents the number of tails that occur. Hence, the random variable Y takes any one value from {0, 1, 2}.
