Question

Let A={ b ,c,d,e}
B={ d,e,f,g } be two subset of the universal set

A) ( b,c,d,e,f,g) then verify following:-

1) ( AᴗB) = (A︵B )

Answer 1

(AUB)=(b,c,d,e)U(d,e,f,g)

=(b,c,d,e,f,g)

(AnB)=(b,c,d,e)n(d,e,f,g)

=(d,e)

=>(AUB) is not equal to (AnB)

I Hope U Understand

PLEASE MARK ME AS A BRAINLIST

Answer 2

Answer:

[AUB]' ≠ [A'∩B']

Step-by-step explanation:

A' = { f,g }

B' = { b,c }

[AUB]' = { b,c,f,g }

[A'∩B'] = {    }

HENCE IT IS VERIFIED THAT [AUB]' ≠ [A'∩B']
