Question 2:
If the set A has 3 elements and the set B = {3, 4, 5}, then find the number of elements in (A × B)?
Answer
It is given that set A has 3 elements and the elements of set B are 3, 4, and 5.
⇒ Number of elements in set B = 3
Number of elements in (A × B) = (Number of elements in A) × (Number of elements in B) = 3 × 3 = 9
Thus, the number of elements in (A × B) is 9.
