Could you help me with one Algebra problem?
Construct the appropriate number sets with the given information. Use the sets to match the following:

Given

a = Ø

b = B

c = then A ∪ B = B

d = A

e = then A ∩ B = B


I have to match these options:

1. If AB
2. If BA
3. A ∪ Ø
4. A ∩ Ø
5. B ∪ Ø

with these options:

c
a
d
b
e

the solutions are
1. If A=B implies c = then A ∪ B = B
2. If B is inside A  e = then A ∩ B = B
3. A ∪ Ø implies  d = A
4. A ∩ Ø imiplies a = Ø
5. B ∪ Ø implies b = B
