Find Each Set?

Use A = {1, 3, 5, 7, 9}, B = {1, 5, 6, 7} and C = {1, 2 ,4, 6, 8, 9) to find each set below.





(1) A ∩ C





(2) (A U B) ∩ C

Find Each Set?
A n C means the point where set A and C intersect or the numbers that they have in common





Ans = {1, 9}





2. (A u B) means the numbers in a union between A and B and is equal to (1,3,5,7,9) now figure out were this new set intersects with n





Ans = {1,9}
Reply:please check the answer you have selected she taking union of A and B is (1,3,5,7,9) but this is wrong it should be (1,3,5,6,7,9) please ask to anyone who knows sets Report It

Reply:1.


A∩C={1,9}


2.


(AUB)∩C={1,3,5,6,7,9}∩{1,2,4,6,8,9}


={1,6,9}
Reply:q1


A ∩ C


= {1,9}





q2


(A U B) ∩ C


= {1,3,5,6,7,9} n {1,2,4,6,8,9}


= {1,9}
