Practice TISS-NET (PG) cartesian_product_relations in the app →Given P = {a, b} and Q = {1, 2}, the cartesian product P × Q isIf n(A) = 3 and n(B) = 4, then n(A × B) =Two ordered pairs (x, y) and (a, b) are equal if and only ifIf (x + 1, y − 2) = (3, 1), then x and y equalR × R, where R is the set of real numbers, representsLet A = {1, 2, 3}, B = {3, 4}, C = {4, 5, 6}. The set A × (B ∩ C) isIf A × B = {(p, q), (p, r), (m, q), (m, r)}, then A and B areLet P = {1, 2}. Then P × P × P contains how many ordered triples?Which statement is TRUE for any non-empty sets P and Q?If A or B is the empty set, then A × B equalsGiven P = {a, b, c} and Q = {r}, the cartesian product Q × P isIf A × B has 6 elements and three of these are (1, 2), (2, 3), (3, 3), then A and B areWhich identity is ALWAYS TRUE for arbitrary sets A, B, C?If P = {m, n} and Q = {n, m}, then P × Q equalsLet A = {1, 2}, B = {3, 4}. Then A × (B ∩ ∅) isIf n(A × B) = pq and (A × B) ∩ (A × C) = A × (B ∩ C), then for which choice is the intersection MAXIMISED?
