Question

Find the universel set if A=(1,3,5,7,9) and A' =(4,5,6,7,12)​

Answer 1

Since A={1,3,5,7,9}

A'={4,5,6,7,12}

Therefore,

Universal Set = U=A U A'

={1,3,4,5,6,7,9,12}

Please follow me.

Answer 2

${\huge{\underline{\underline{\sf {\mathfrak{Answer}}}}}}$

${\underline{\underline{\rm {Given:}}}}$

• $A =${ $1,3,5,7,9$}
• $A' =${ $4,5,6,7,12$}

${\underline{\underline{\rm {Solution:}}}}$

$U - A = A'$

$U = A + A'$

$U =${ $1,3,5,7,9$}$+${ $4,5,6,7,12$}

$\boxed{\implies{\boxed{U = {1,3,4,5,6,7,9,12}}}}$
