Answer 1

Answer:

Correct options are B and C.

Step-by-step explanation:

Let us understand this with the help of a venn diagram.

so in the attached picture: A ⊆ B [A belongs to B or A is a subset of B ]

A = White,

B= A + yellow,

U(universal set) =  B + Blue.

A' = Area in yellow and blue colour.

B' = Area in blue colour

According to the given options:

(A) A' ⊆ B [white + blue + yellow belongs to blue + white] which is False

rather it should be B ⊆ A' i.e B is a subset of A'

(B) B' ⊆ A' [Blue belongs to yellow + blue], True

(C) A ∩ B' = φ [White is not intersecting blue], True

(D) A' ∩ B = φ [yellow + blue is not intersecting yellow ], False
