The answer depends on the Venn diagram.
To create a Venn diagram using the union of sets A and B, you would first draw two overlapping circles to represent sets A and B. The union of sets A and B, denoted as A ∪ B, includes all elements that are in either set A, set B, or both. Therefore, in the Venn diagram, you would shade the region where the circles overlap to represent the elements that are in both sets A and B, as well as the individual regions of each circle to represent elements unique to each set.
Draw a circle.Using any point on the perimeter of that circle as your center, draw another circle of the same radius.Using either of the two points where the perimeters of those circles intersect as your center, draw a third circle of the same radius.Fill in all three circles.You now have a Venn diagram for A ∪ B ∪ C
A or B or C = A + B + C - A and B - A and C - B and C - 2 (A and B and C) I'm not sure by the way;
Draw your Venn Diagram as three overlapping circles. Each circle is a set. The union of the sets is what's contained within all 3 circles, making sure not to count the overlapping portion twice. An easier problem is when you have 2 sets, lets say A and B. In a Venn Diagram that looks like 2 overlapping circles. A union B = A + B - (A intersect B) A intersect B is the region that both circles have in common. You subtract that because it has already been included when you added circle A, so you don't want to add that Again with circle B, thus you subtract after adding B. With three sets, A, B, C A union B union C = A + B - (A intersect B) + C - (A intersect C) - (B intersect C) + (A intersect B intersect C) You have to add the middle region (A intersect B intersect C) back because when you subtract A intersect C and B intersect C you are actually subtracting the very middle region Twice, and that's not accurate. This would be easier to explain if we could actually draw circles.
Venn diagram is represented with the help of circles. Union of a, b and c is shown by the three fully shaded somewhat overlapped circles. Result will be the elements that is in all three sets(a,b,c).

Assuming you're joining on columns with no duplicates, which is by far the most common case; An inner join of A and B gives the result of A intersect B, i.e. the inner part of a venn diagram intersection. Wheres as an outer join of A and B gives the results of A union B, i.e. the outer parts of a venn diagram union.

If B = {10111213} and C = {1213} then their intersection is the empty set, {}.The union of A with an empty set is set A.
In a two part Venn diagram of an or function the center intersection would have to be shaded. This is because you result can be A or B.
A or B or C = A + B + C - A and B - A and C - B and C - 2 (A and B and C) I'm not sure by the way;

the circles do not overlap at all.
An element in the set A or B is one that is in the union of the two sets. It can be in A or B or both.
