Here's the Solution to this Question

1)

What are the elements of D, E, and F?

Elements of D = 3,19,15

Elements of E = 3,15,19

Elements of F = 3, 3,9, 15, 15


How are D, E,  and F related?       

  They both comprise of elements which are divisible by three.


2)


1 is an element, {2} is an element, [1,2} is an element .


Hence,we conclude that there are three elements.


3) since Bp consists of two elements, the power set = 22 = 4 elements

Thus B1 = { p2]

B2 = {P3]

B3= {P2,P3]
