Refer to the diagram to answer the questions below. What set notation would you use to represent the following regions? Example: Region 3 could be written as A B. i) Regions 1, 2 and 4 are all shaded. (A ∩ B)’ or A’ B’. iii) Only Region 1 is shaded. (A B)’ or A’ ∩ B’. ii) Only Region 2 is shaded.
SET INTERSECTION, SET UNION, SET COMPLEMENT: SUMMARY. The intersection of two sets denotes the elements that the sets have in common, or the "overlap" of the two sets. S ∩ T = {x|x∈ S and x∈ T}. The union of two sets merges the two sets into one "larger" set. S ∪ T = {x|x ∈ S or x ∈ T}.
Worksheet on operation on sets we will solve 10 different types questions on math sets. 1. Find the union of each of the following pairs of sets. (a) A = {2, 4, 6} B = {1, 2, 3}
Basic discrete structures. Discrete math =. study of the discrete structures used to represent discrete objects. Many discrete structures are built using sets. Sets = collection of objects. Examples of discrete structures built with the help of sets: Combinations.
A set is a collection of numbers or objects. For example, if W is the set of the fi rst ten whole numbers then this can be written as: W {1, 2, 3, 4, 5, 6, 7, 8, 9, 10} The whole numbers from 1 to 10 are the members of set W. A picture called a Venn diagram is used to represent sets and show the relationship between them.
Describing a Set 1. R = {a, e, i, o, u} Answer : The set R is a list of vowels. 2. G = {0, 1, 2, 3, 4, 5, 6, 7, 8, 9} Answer: G contains whole numbers less than 10. 3. D = {a, b, c, d, e, f, g, h, i, j, k, l, m, n, o, p, q, r, s, t, u, v, w, x, y, z} Answer: D contains letters in the English alphabet. Listing a Set 1.
Section 1.6: Venn Diagrams and set operations In this section we will be given Venn diagrams that have elements inside them. It is important to be able to create the sets described by a Venn diagram. Example: Write down the elements of the sets U, A and B. The elements of U are each number in the diagram. U = {1,2,3,4,5,6,7,8,9,10}
