Need confirmation regarding the solution of a simple probability question related to deck of cards?

Example 5: Two cards are drawn from a deck of cards.

A: 1 s t card is a club

B: 1 s t card is a 7

C: 2 n d card is a heart.

Find the following probabilities:

(a) P(A or B)

(b) P (B or A)

(c) P (A and C)

I can easily solve (a) and (b). But for (c) the solution in my book is as follows-

But I think it is not right. Because if the first card is a club the only 51 cards would be remaining. So it should be $$13\div52*13\div51$$.

Please correct me if I am wrong or the book solution is wrong. I just need confirmation regarding this question.
