Question

If A = { 2,3,5,7 } then find the value of n(A).

Answer 1

We conclude that

• n(A) = 4

Explanation:

Given the set

• A = { 2,3,5,7 }

If we closely observe, we can easily identify that set A has 4 elements, which are 2, 3, 5, and 7.

n(A) denotes the number of elements in a set.

Since set A has 4 elements, therefore the value of n(A) = 4

Thus, we conclude that

• n(A) = 4
