U = {1,2,3,…10} A={2,5,7,9}, B= {3,5,7,9,10}, C = {x€U :1

Solution:

C={x € U : 1}

==> U= {x: x is an odd positve integer}

x € U it means x is elament of U...

A{2,5,7,9}:

==> A set have n(4) elements and

==> A={x:x is an odd positive integer}

==> It means A is the consisting of the numbers 2,3,5 and 9 .the element if the set are seperated by commas and enclosed in braces{ }.

==> This is called the tabular form or roster method of set.

B{3,5,7,9,10}:

==> B set contains n(5) elements

==> B = {x: x is an odd positive integar, x<10}

==>It means B is the consisting of the numbers 3,5,7,9 and 10 .the element if the set are seperated by commas and enclosed in braces{ },
