Question

Could you help with a Algebra problem (unions and intersections)? Got stuck on this ninth one.

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


1. If A union B
2. A union C
3. A intersect B
4 . A intersect C
5. B intersect C

Answer 1

1) If A c B matches with c. then A ∪ B = B
2) If B c A matches with e. then A ∩ B = B
3) A ∪ Ø matches with d. A
4) A ∩ Ø matches with a. Ø
5) B ∪ Ø matches with b. B
