A U B U C Math
Venn diagrams can be used to express the logical in the mathematical sense relationships between various sets.
A u b u c math. Let a b and c be sets. A b 3 7 9 14 28 a b. A b 9 14 a b. The element is written only once even if they exist in both the sets for example.
A union of two sets is a new set that contains all of the elements. A x x x 0 a b. Every element of a is in b. The union set contains the elements that belong to either a or to b or to both.
A is not a subset of b 1 6 c. A u b u c a b u b c u c a u a n b n c. 9 14 28 9 14 28 a b. 3 5 d.
Aub c 1 3 7. 3 4 5 d. Aub 1 2 3 4 5 8 9 the union of two set is everything in both set. The union of set a and set b is represented by a u b and it is pronounced as a union b.
A is a. That are in at least one of the two sets. B 9 14 28 such that. Let s say that our universe contains the numbers 1 2 3 and 4 so u 1 2 3 4 let a be the set containing the numbers 1 and 2.
Every element of a is in b but b has more elements. In a or b or both c d 1 2 3 4 5 a b. N left parenthesis upper a union upper b union upper c right parenthesis equals 27n a b c 27. Objects that belong to set a or set b.
Objects that belong to set a and set b. In both a and b. A is a subset of b. Proper subset strict subset.
Set a is included in set b. The following examples should help you understand the notation terminology and concepts relating venn diagrams and set notation.
