Venn Diagrams Name__________________________ Answer the following based on sample space using a Venn Diagram. 1. Use the sets below to answer parts (a) through (f): U = {1, 2, 3, 4, 5, 6, 7, 8, 9. 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20} A = the numbers in U that divide 12 with no remainder B = the numbers in U that divide 15 with no remainder C = the numbers in U that divide 20 with no remainder a. A B d. A B b. B C e. A C c. A B C f. A B C 2. Make and label a Venn diagram for the following data where A, B, and C are subsets of the universe of people who were surveyed about the type of meat they like to eat. Let A represent the people who like steak, B is the set who like chicken, and C is the set who like pork. n(U) = 350 n(A) = 150 n( B) = 195 n( C) = 170 n(A B) = 99 n(B C) = 103 n(A C) = 62 n(A B C) = 56 Given the following Venn Diagram, answer #3. 3. Find the following a. A B C _______________ b. B A _______________ c. A B c a,b h d B C A _______________ f,g e i, j d. C _______________ C 4. Shade the following on the Venn Diagrams below. a.

Make and label a Venn diagram for the following data where A, B, and C are subsets of the universe of people who were surveyed about the type of food they like to eat. Let A represent the people who like hamburgers, B is the set who like hot dogs, and C is the set who like pizza. n(U) = 400 n(A) = 150 n( B) = 140 n( C) = 120 n(A B) = 70 n(B C) = 90 n(A C) = 50 n(A B C) = 30 U = {a, b, c, d, e, f, g, h} 8. Create a venn diagram and then answer the questions. a. A B e. A C b. B C f. A B C c. A B g. B C d. AC B h. B C A = {a, c, e} B = {b, c, d} C = {c, e, h}
