Question

If U={x|x ∈ N,x<5} and A={x|x ∈ N ,x ≤ 2 } then A'=______
A){1,2}
B){1,2,3,4,5}
C){3,4}
D){3,4,5}

Answer 1

HI FRIEND

U = [ 1, 2, 3, 4 ]
A = [ 1, 2]

so, A' = [ 3, 4 ]

The answer is C) [ 3, 4 ]

HOPE IT HELPS

Answer 2

Hi ,

U = { 1 , 2 , 3 , 4 }

A = { 1 , 2 }

A' = U - A

= { 1 , 2 , 3 , 4 } - { 1 , 2 }

= { 3 , 4 }

Option ( C ) is correct

I hope this helps you.
