B= { x is an element of natural numbers | x is a multiple of 3 }
D = { x is an element of natural numbers | x is even }
Use the roster method to list all of the elements in this set.

B U D
This is what I came up with .
{ 1,2,3,4,5, 7,8,9,10,11, 13,14,15,16,17,...........}
Solution
B= { x is an element of natural numbers | x is a multiple of 3 }
B ={ 3,6,9,.......}
B' = { 1,2,4,5,7,8,.........
D = { x is an element of natural numbers | x is even }
D = { 2,4,6,8,.........}
D' = {1,3,5,7}
Use the roster method to list all of the elements in this set.

B U D = u r correct.
