Question

Find n(A) for the set.

17) A-16, 8, 10, 12, 14)
A) n(A)=4
B) n(A)=5
C) n(A)=3
D) n(A)=2

Answer 1

The number of elements in set A, which is {16, 8, 10, 12, 14}, is 5. Therefore, the correct answer is B) n(A) = 5.

Step-by-step explanation:

The question is asking to find the number of elements (n(A)) in the set A. The given set is A = {16, 8, 10, 12, 14}. To determine n(A), we simply count the number of distinct elements in the set.

• 16
• 8
• 10
• 12
• 14

Counting these elements, we see that there are 5 distinct numbers in set A. Therefore, n(A) = 5, which makes option B) n(A) = 5 the correct answer.
