यदि A और B दो गैर-रिक्त समुच्चय हैं जैसे कि n(A) = p और n(B) = q तो संबंधों की संख्या जो A से B तक परिभाषित की जा सकती है = 2 pq
गणना :
दिया गया: A = {x, y, z} और B = {1, 2}
⇒ n(A) = 3 और n(B) = 2
जैसा कि हम जानते हैं कि यदि A और B दो गैर-रिक्त समुच्चय हैं जैसे कि n(A) = p और n(B) = q तो संबंधों की संख्या जो A से B तक परिभाषित की जा सकती है = 2 pq
यहां, p = 3 और q = 2
तो, A से बी तक संबंधों की संख्या = 26
इसलिए, विकल्प 2 सही उत्तर है।
