Question
If a set A has 3 elements and B has 6 elements such that A ⊆ B then the number of elements in A ∩ B = ?
Solution
Sure, let's solve the problem step by step.
Step 1: Given that set A has 3 elements and set B has 6 elements, and A is a subset of B.
Step 2: To find the number of elements in the intersection of A and B (A∩B), we need to determine the common elements between the two sets.
Step 3: Since A is a subset of B, all the elements in A must also be present in B. Therefore, the number of elements in A∩B is equal to the number of elements in A, which is 3.
So, the number of elements in A∩B is 3.
