Question

Ven Diagrams with union and intersection problems shading in diagram

Answer 1

Answer:

4 types of questions one will be to read, 2nd will be to subtract, one will be to add, the next will be to find missing numbers each are expressed below.

Step-by-step explanation:

This is a two-circle Venn diagram. The 1st circle is A, and the 2nd circle is B. The complete Venn diagram represents the union of A and B, or A ∪ B.

Just intersect is A ∩ B

Just intersect B ∩ A

A∩B=   A∩B={2}  differs significantly from below.

A  small ∁

 (sometimes denoted as ~A or ¬A)

is pronounced as: "A complement" (or "not A", for the other notations)

means: the new set gets everything that is in the universe but is outside of A; it's okay if the element is in B, just so long as it is not also in A

in terms of the elements: {1, 2, 3, 4} – {1, 2}

my answer:  = A ∁ ={3,4}

A – B (or A \ B)in terms of the elements: {1, 2} – {2, 3}

A – B = {1}

A∪B)=¬(A∪B)in terms of the elements: = {1, 2, 3, 4} – {2}

in terms of the elements: {1, 2, 3, 4} – ({1, 2} ∪ {2, 3}) = {1, 2, 3, 4} – {1, 2, 3}

(4) elements here are just the remainder my answer: my answer:(A∪B)={4}
