Let A = {1, 2, 3, 4, 5, 6}. Which of the following statements is correct?
A5 ∈ A and 8 ∉ A
B0 ∈ A and 10 ∈ A
C8 ∈ A and 2 ∈ A
D5 ∉ A and 4 ∉ A
Answer & Solution
Correct answer: A. 5 ∈ A and 8 ∉ A
Of the listed numbers, only those between 1 and 6 inclusive belong to A. Hence 5 ∈ A and 8 ∉ A. Each of the other statements asserts a false membership claim.
