Expert Solution
Step 1

(a) Given for set APA=ϕ,3,5,6,3,5,3,6,5,6,3,5,6

We have to find the set A

Hence, A=3,5,6

(b) Given set B is removed from the set P2,4,8,9 then the following set is obtained

ϕ,2,4,8,9,2,4,2,8,2,9,4,8,4,9,8,9,2,4,8,2,4,9,4,8,9,2,4,8,9

Now write the set P2,4,8,9, which is given below

P2,4,8,9=ϕ,2,4,8,9,2,4,2,8,2,9,4,8,4,9,8,9,2,4,8,2,4,9,2,8,9,4,8,9,2,4,8,9

Now remove the set ϕ,2,4,8,9,2,4,2,8,2,9,4,8,4,9,8,9,2,4,8,2,4,9,4,8,9,2,4,8,9 from P2,4,8,9=ϕ,2,4,8,9,2,4,2,8,2,9,4,8,4,9,8,9,2,4,8,2,4,9,2,8,9,4,8,9,2,4,8,9, we get

B=2,8,9
