A day without Math is like a day without sunshine!
Hi Courtney,
find the set A U B
U= {1,2,3,4,5,6,7,8,9}
A= {2,4,5,6}
B= {1,4,3}
U= {1,2,3,4,5,6,7,8,9}
A= {2,4,5,6}
B= {1,4,3}
The question is asking for the union of sets A and B. This means to combine the sets. Since 4 is an element common to both sets, only show it once.
A U B = {1,2,3,4,5,6}
Hope that helps.
