Two Sets That Contain the Same Number of Elements Are Called


Question: Two sets that contain the same number of elements are called_____

The question is based on the operation of sets.

Answer: Two sets that contain the same number of elements are called equivalent sets.

Let's understand the size of a set or the cardinality of a set.

Explanation:

The number of elements in a set defines the cardinality of a set. For a set A, cardinality is defined as n(A). 

Set A = {1, 2, 3, 4, 5}, Hence, n(A) = 5

Set B = {a, b, c, d, e}, Hence, n(B) = 5

Then we can say that Set A and Set B are equivalent or of the same cardinality.

Thus, if n(A) = n(B), that means two sets that contain the same number of elements, then we call A and B as equivalent sets.
