1. Determine whether each statement is true or false. Enter T for True, F for False.

A) The set {9, 0, 2, 1, 0} contains 5 elements.

B) The two sets {c, s, n} and {n, s, c} are equal.

C) The universal set, being the largest set, contains everything in the universe.

D) The notation for the empty set is {}.

2. When entering sets, follow these rules:(i) Use the Roster notation, like {x,y,z}. (ii) List elements from small to large, so {2,3,7} is good, but {3,7,2} is not good. (iii) Use a comma between consecutive elements, but do not add spaces. (iv) Do not use a comma after the last element. (v) Use one space inside the cursive brackets for the empty set: { }.

GivenU= {1, 2, 3, 4, 5, 6, 7, 8, 9, 10},A= {1, 3, 5, 7, 9},B= {2, 4, 6, 8, 10},C= {2, 3, 5, 7} andD= {6, 7, 8, 9, 10}, find the following sets.

A)ACAC

B)ACAC

C)DD

D)BDBD

3. GivenU= {a, b, c, d, e, i, o, u},A= {a, b, c, d, e},B= {a, e, i, o, u},C= {i. o. u}, find the following sets.

A)ACAC

B)ACAC

C)(AB)(AB)

D)ABAB

4. Determine whether each statement is true or false. Enter T for True, F for False. HereUUis the universal set,AAandBBare two sets.

A)AA=UAA=U

B)AA=AA=

C)(AB)=AB(AB)=AB

D)(AB)=AB(AB)=AB
