Question

If d(A, B)=5 d(B, C)=2 d(A, C)=3 then which of the following option is true? 1 point A-C-B A-B-C C-A-B None of these​

Answer 1

Step-by-step explanation:

Correct option is

D

Both(1) and (3)

For the given sets,

(A∪B)= { a,b,c,d,e,g}    (Combination of all elements of both sets)

Clearly, elements of C are a part of A∪B as well,

So, C⊂(A∪B)

And, (A∩B)= { a,c,e}   (Common elements of both sets )

As the elements of C are  not completely a part of A∩B , Option B is not True.

Also,

(A∪C)= { a,b,c,d,e,g}

Clearly, (A∪B)=(A∪C)

Hence, both first option and third options are True.
