I do not under stand where the 6,7,8,and 9 comes in if there are only five vertices (A1, A2, A3, A4, and A5. This is the answer that was posted to the question \"A1 = {0, 2, 4, 6, 8}, A2 = {0, 1, 2, 3, 4}, A3 = {1, 3, 5, 7, 9}, A4 = {5, 6, 7, 8, 9}, A5 = {0, 1, 8, 9} Here by set, A1 is not connect A3,A2 is not connect A4, A3 is not connect A1 and A1 is not connect A3. and other all connected each other. \"

Solution

Given 5 vertices means A1,A2,A3,A4,A5

not the elements inthe sets

the numbers in vertices might be anything not only 6,7,8,9 but also it can be 100,200,99,10

vertices means A1,A2,A3,A4,A5 remember

The numbers inside the vertices shows their behaviour and numbers represents the sets

A1 is even A3 is odd they dont connect
