Chake Answer Exercises 1.3 Page 12 4. Given A = {1,2,3,4} Write the subset from one element , and two elements Subsets formed from one element is {1}, {2}, {3}, {4} Subsets formed from two elements are {1,2}, {1,3}, {1,4}, {2,3}, {2,4} {3,4}
Example Given A = {1,2,3,4} and B = {3,4,5,6} , Write the Venn Diagrams U A B 1 3 5 2 4 6
Example Given U= {a,b,c,…,z} and A = {a,b,c,d} B = {e,f,g}, andC={h,i,j,k} Write the Venn Diagrams A B a b e f c d C g h i j k
Example Given U = {x:x natural number less than 20} A = {x:x natural number less than 7} B = {x:x positive odd number less than 7} Write the venn diagrams Solutions U = {1,2,3,…,19} A = {1,2,3,4,5,6} B = {1,3,5} U 6 7 A 9… 8 1 B 4 5 3 2 19
Venn Diagrams Venn Diagrams are visual representations regarding the Relationship between sets The universal set U is shown by a rectangle , subset of the Universal set are drawn as ovals or circles inside the rectangle And arae usually labelled with a capital letter U A
U For example U= {all cars} A A= {red cars} The circular region A in the Venn diagram represents the set of red cars which are not red are represented by the green region
The following Venn diagrams show how two sets A and B (which are subsets of U) can be related Set B is a subset of set A , so B is drawn inside A U B A
Home work Exercises 1.3 Page… 13 5.Which the following given that U is a natural Number , draw a Venn diagrams 1. A={1,2,3,4,…,10} 3. A={1,2,3,4,…,10} B={1,3,5,7,9} B={1,3,5} 2. A={1,2,3,4,…,10} C={2,4,6} B={1,3,5,7,9} C={1,3,5}
