Question

TRY THIS
List out some sets A and B and choose their elements such that A and B are disjoint
IfA= {2, 3, 5), find AU 0 and OU A and compare.
IfA= {1,2,3,4}; B= {1, 2, 3, 4, 5, 6, 7, 8} then find AUB, AB. What do you
notice about the result?
A = {1, 2, 3, 4, 5, 6}; B = {2, 4, 6, 8, 10}. Find the intersection of A and B.

Answer 1

Answer:

Step-by-step explanation:

A={2,3,5}

AU O = { 2,3,5}. O UA={2,3,5}

Because the O set have no elements.

A={1,2,3,4} B={1,2,3,4,5,6,7,8}

AUB={1,2,3,4,5,6,7,8}

In this question A is subset of B. So AUB=B.

A={1,2,3,4,5,6}. B={2,4,6,8}

A intersection B ={2,4,6}
