Question

ifA=(1,3,9,11,13)andB=(1,9,11)then find AUB and ANB​

Answer 1

⇒A = { 1,3,9,11,13 }

B = { 1,9,11 }

⇒ AUB = { 1,3,9,11,13 } U { 1,9,11 }

{ 1,3,9,11,13 }

= A

⇒ii ) A n B = { 1,3,9,11,13 } n { 1,9,11 }

{ 1 , 9 , 11 }

= B

• ifA=(1,3,9,11,13)and
• B=(1,9,11)

${\sf{\green{\underline{\large{To\:find}}}}}$

• AUB and A$\Cap$B

${\sf{\pink{\underline{\Large{Explanation}}}}}$

First Explanation

U = Union :- In this case We have to take All the Element from Given no

A=(1,3,9,11,13) B=(1,9,11)

A U B = {1,3,9,11,13}

Second Explanation

$\tt{A\cap{B}}$= Intersection :- In this case we have to take Common point between two no

A=(1,3,9,11,13) B=(1,9,11)

$\tt{A\cap{B}}$={1,9,11}
