Let U 3 4 5 6 7 8 9 10 11 12 A 3 5 7 9 11 B 4 6 8 10 12 a

Let

U = {3, 4, 5, 6, 7, 8, 9, 10, 11, 12},

A = {3, 5, 7, 9, 11},

B = {4, 6, 8, 10, 12},

and

C = {3, 4, 6, 7, 10, 11}.

List the elements of each set. (Enter your answers using roster notation. Enter EMPTY or ? for the empty set.)

(a)    C ? C?^c


(b)    (A ? C)^c


(c)    A ? (B ? C)

Solution

a.) EMPTY
b.) {4,5,6,8,9,10,12}
c.) {3,4,5,6,7,9,10,11}
