- 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.

What is the formula for a Venn Diagram?
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;
How do you find the venn diagram for union of three sets?
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.
What is the complement of the union B and C?
not (b or c) = (not b) and (not c)
Is it true that if a union c equals b union c then a equals b?
No- this is not true in general. Counterexample: Let a = {1,2}, b = {1} and c ={2}. a union c = [1,2} and b union c = {1,2} but a does not equal b. The statement be made true by putting additional restrictions on the sets.
Prove A union B minus A intersection B equals A minus B union B minus A?
complement of c
What is the venn diagram of a union b union c?
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).

How will you write using the venn diagram the union of set a(1234) and the intersection of set b(10111213) and set c(1213)?
If B = {10111213} and C = {1213} then their intersection is the empty set, {}.The union of A with an empty set is set A.

Draw a Venn diagram to test the argument form below for validity. Write "valid" or "invalid" next to the diagram to indicate the result of your test.All D are C. All C are B. So, No D are B?
invalid

make a venn diagram of set AB/C group of add number
How do you solve A intersecting B union C?
The answer depends on whether you mean A intersecting (B union C) or (A intersecting B) union C.
What is the complement of the union B and C?
not (b or c) = (not b) and (not c)
Is it true that if a union c equals b union c then a equals b?
No- this is not true in general. Counterexample: Let a = {1,2}, b = {1} and c ={2}. a union c = [1,2} and b union c = {1,2} but a does not equal b. The statement be made true by putting additional restrictions on the sets.
Prove if a union c equals b union c and a intersect c equals b intersect c then a equals b?
suppose x is in B. there are two cases you have to consider. 1. x is in A. 2. x is not in A Case 1: x is in A. x is also in B. then x is in A intersection B. Since A intersection B = A intersection C, then this means x is in A intersection C. this implies that x is in C. Case 2: x is not in A. then x is in B. We know that x is in A union B. Since A union B = A union C, this means that x is in A or x is in C. since x is not in A, it follows that x is in C. We have shown that B is a subset of C. To show that C is subset of B, we do the same as above.
