x is the shaded portion between the intersection of 3 circles A, B, and C. All options are true about x except the first one.
What is set?
A set is simply an organized collection of distinct objects forming a group and can be expressed in set-builder form or roaster form.
In the given three-set Venn diagram
we can see that x is the shaded portion between the intersection of 3 circles A, B, and C. We need to find which statements are true for x.
hence x ∈ A, x ∈ B, x don't belong to C, and x ∈ A union B, x ∈ A union C, and x ∈ A intersection B.
Thus option 1 is not true about x. x ∈ B, x ∈ A∪B, x ∈ A∪C, x ∈ A∩B are true.
