Question

Note: Answer all questions. Each question carries two mark 3X2 = 6

5. P = { x: x is a factor of 9} then write all subsets of P?

6. If Q = ={x: x €N, x< 4} and R = {x : x is a factor of 12}. Represent this in

7. C and D are two sets such that C ={x: x is an odd prime <12}

D ={x: x is an even number <12}. Verify that C and D are disjoint or not?​

Answer 1

all the subsetd of p = {1},{3},{9},{1,3,9},{1,3},{3,9},{1,9},{ }

C = { 3,5,7,11 } and D = { 2,4,6,8 }

C intersection D = { }

hence C and D are disjoint sets
