Question

if setA=(even numbers<10) setB=(odd numbers<10).write them in roster form and find A-B,B-A and represent them in venn diagram.

Answer 1

setA={even numbers less then 10}
setB={odd numbers less then 10}
setA={0,2,4,6,8}
setB={1,3,5,7,9}
set{A×B}={(0,1)(0,3)(0,5)(0,7)(0,9)(2,0)................(8,9)

Answer 2

A={0,2,4,6,8} ; B = {1,3,5,7,9 }
A-B = {0,2,4,6,8} - {1,3,5,7,9}
A-B = { 0,2,4,6,8 }

B-A = {1,3,5,7,9} - {0,2,4,6,8}
B-A = { 1,3,5,7,9 }
