Question 40692: Intersections and Unions
If p={-3,-2,0,1,5}
T={0,1,6,9}
and S={-3,1,6}
find T U S
How do i do This?
Thank you

You can put this solution on YOUR website! Intersections and Unions.
First we must understand that a union includes ALL the terms expressed by each variable.
An Intersection includes only those terms that are contained in both variables.
So...
If p={-3,-2,0,1,5}
T={0,1,6,9}
and S={-3,1,6}
find T U S
We need to find the Union of T = {0,1,6,9} and S = {-3,1,6}
So if we follow our rules for Unions we must include ALL the terms expressed by each variable.
So...
T U S = {-3,0,1,6,9}
NOTE: We only have to list each number once.
If this problem asked for the Intersection of T & S we would have...
T & S = {1,6} because these are the only terms that are included in both variables.
I hope this helps.
Good Luck!
