### High School Mathematics8.8 Problems on Relations

 Example: If A = {1,3,5}, B = {2,4} and C = {1,2,3,4}, then find A ´ (B È C). Solution: Given that, A = {1,3,5}, B = {2,4} and C = {1,2,3,4} To find A ´ (B È C) first we want to find the value of B È C B È C = {2,4} È {1,2,3,4} = {1,2,3,4} A ´ (B È C) = {1,3,5} ´ {1,2,3,4} = {(1,1),(1,2),(1,3),(1,4),(3,1),(3,2),(3,3),(3,4),(5,1),(5,2),(5,3),(5,4)} Directions: Solve the following problems. Also write at least 5 examples of your own.
