    so the range of x is (0,1), while the range of y is (0,1,2), as explained in the above comment.

    range of x is directly written in the question itself. x depends on first toss only. if first toss results in head, x=1, but if first toss results in tail, x=0. But y depends on both toss, we can say about y only after both the toss have been done. Now concentrate on what I am going to say. After two toss, what could be the cases for head. case 1) No head in both toss hence y=0, case2) one head and one tail in the two toss, hence number of head is one, y=1. case3) when both the toss result in head, number of heads = 2, hence y=2.
