Consider the sets below.

-U x
-A x
-R x is red, yellow, or blue
Is R ⊂ A?

Answer 1

The answer is B!!!!!!!

Answer 2

Yes R ⊂ A.

Explanation:

We are given a set U as:

--- U= x

--- A= x is a color of the rainbow

We know that a rainbow has seven colors named as VIBGYOR

where V-- Violet

I-- Indigo

B-- Blue

G-- Green

Y-- Yellow
