If n(A)=2 and n(B)=5 then what is n(A × B)?
यदि n(A)=2 और n(B)=5 है तो n(A × B) कितना होगा?
Show answer and explanation
Correct Answer
B. 10 / 10
ExplanationStep 1: Ordered pairs are counted in Cartesian product. Step 2: n(A × B) = n(A) × n(B) = 2 × 5 = 10. Step 3: Each element of A pairs with each element of B.
Step 1: Cartesian product में ordered pairs गिने जाते हैं। Step 2: n(A × B) = n(A) × n(B) = 2 × 5 = 10। Step 3: हर element of A हर element of B से pair बनाता है।
