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)}
