Question

If A={x:x is amultiple of 2 less than 10} B= {x:x is a factors of 10} then find AUB and AnB

Answer 1

Solution :

A = { x:x is a multiple of 2<10 }

=> A = { 2,4,6,8 }

B = { x:x is a factors of 10 }

B = { 1,2,5,10 }

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

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

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

= { 2 }
