U = {x : x < 6 , x ∈ N}, A = { x : x এবং 1 < x ≤ 4} হলে A' = কত?
Solution
Correct Answer: Option D
U = {x : x < 6 , x ∈ N}
A = { x : x এবং 1 < x ≤ 4}
U = {1, 2, 3, 4, 5}
A = {2, 3, 4}
A' = U - A
={1, 2, 3, 4, 5} - {2, 3, 4}
= {1, 5}
A = { x : x এবং 1 < x ≤ 4}
U = {1, 2, 3, 4, 5}
A = {2, 3, 4}
A' = U - A
={1, 2, 3, 4, 5} - {2, 3, 4}
= {1, 5}
