Question

If A={1,3,9,11,13} & B={1,9,11} then find AUB & AUB

Answer 1

Solution:

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

B = { 1,9,11 }

i ) 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

If A={1,3,9,11,13} & B={1,9,11} then find AUB & AUB


$\bold{\underline{Answer-}}$

Given that -

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

Need to find -

A U B = ?
A ∩ B = ?

A U B => we know that Sets are mixed where there is a union

then, {1,3,9,11,13}U{1,9,11} = {1,3,9,11,13}

A ∩ B => we know that where intercession we write only common sets

then, {1,3,9,11,13} ∩ {1,9,11} = {1,9,11}
