Help me please Let U is a set of natural numbers less than 20 (x<20)
A = set of even numbers in set U
B = {odd natural numbers less than 12}
C = {Multiples of 5 between 5 and 15, inclusive}
D = {Multiples of 3 greater than 4 and less than 20}

Write all elements of the next sets:
Example. A={2,4,6,8,10,12,14,16,18}
B =
C =
D =
A’=
A∪B=

D∩B=

A’\ D=
