6. (10 points) Let A, B, and C be sets. Prove (AuB)C(AnC) u(BnC)
Please help me prove 2,4, and 5. Thank you Theorem 17. Let A, B and C be sets. Then the following statements are true: (1) AB CA; (2) B CAUB; (3) A CAUB; (4) AB=BA; (5) AU (AUC) = (AUB) UC; (6) An(BNC) = (ANB) nC; (7) An (BUC) = (ANB) U (ANC); (8) AU (BAC) = (AUB) n(AUC).
Given the following sets, find the set AU(BNC). U = {1, 2, 3, ..., 10; A = {1, 2, 3, 4 B = {2,3,4} C = {1, 2, 4, 5, 6) Select the correct choice below and, if necessary, fill in the ans in DA. AU (BOC)= [] (Use a comma to separate answers as needed. Use asc 01 OB. AU(BOC) is the empty set.

Exercise 4. By writing AU BUC as (AUB) UC, show that the Principle of Inclusion-Exclusion for three sets is P(AUBUC) = P(A)+P(B)+P(C)- P(ANB) - P(ANC) - P(BNC)+P(ANBNC) Can you generalize the result to an arbitrary number of events?
