Question 185168: Given A = {1, 2, 3}, B = {3, 4, 5, 6,}, and C = {3, 5, 7}. Evaluate each set
a) A ∩ B
b) A ∩ C
c) A U C
d) B U C
e) (A U B) ∩ C
f) A U (B U C)
g) (A ∩ B) ∩ C
h) (A ∩ B) U C

You can put this solution on YOUR website! Given A = {1, 2, 3}, B = {3, 4, 5, 6,}, and C = {3, 5, 7}. Evaluate each set
a) A ∩ B
b) A ∩ C
c) A U C
d) B U C
I will do a to d. You can do the rest.
∩ = intersection
U = union
For c and d, we need to find all the elements found in the given sets.
(c) A U C = {1, 2, 3, 5, 7}
(d) B U C = {3, 4, 5, 6, 7}
Notice that I did not repeat numbers.
=====================================
For a and b, we need to find the common elements that are found in the given sets.
(a) A ∩ B = {3}
(b) A ∩ C = {3}
You can do the rest.
