Question

If P and Q are two non empty set such that P={a, b, c, d} and Q={1, 2, 3} then find (P × Q).
a. 8 b. 1 c. 12 d. 10

Answer 1

Given:

P = {a, b, c, d}

Q = {1, 2, 3}

To find

(P×Q)

(P×Q) = {a, b, c, d} × {1, 2, 3}

         = { (a, 1), (b, 1), (c, 1), (d, 1), (a, 2), (b, 2), (c, 2), (d, 2), (a, 3), (b, 3), (c, 3), (d, 3) }

Ans: Option C --> 12
