Question:
U is {-5,5} and A is {-3,5} . Find A' (A complement)?
Solution:
U = {-5, 5}
A = {-3, 5}
Complement of A, A' = {-5}
Explanation:
Let there be any set A.
The complement of A set means the elements which are not in A set.
In the above question there is a Universal set(U) given and also A set. Now, the elements which A set doesn't have from universal set that will be complement of A (A').
A' = {x | x ∈ U and x ∉ A}
This set can also be symbolized as U - A
