Question

a=2,4,6,8,10,b=1,3,5,15 find a union b, a intersection b, a-b, b-a​

Answer 1

Given A = { 2,4,6,8,10 } and

B = { 1,3,5,15 }

i ) A U B = { 2,4,6,8,10 } U { 1,3,5,15 }

= { 1,2,3,4,5,6,8,10,15 }

ii ) A n B = { 2,4,6,8,10 } n { 1,3,5,15 }

= { }

= Null set

iii ) A - B = { 2,4,6,8,10 } - { 1,3,5,15 }

= { 2,4,6,8,10 }

= A

iv) B - A = { 1,3,5,15} - { 2,4,6,8,10 }

= { 1,3,5,15}

= B

Answer 2

• A U B = (1,2,3,4,5,6,8,10,15)
• A intersection B = ( )
• A - B = (2,4,6,8,10)
• B-A = (1,3,5,15)
