Question

DEE
A' = {........} B' = {........}
vity I: Fill in the blanks with elements of that set.
U= {1, 3, 5, 8, 9, 10, 11, 12, 13, 15}
A = {1, 11, 13; B = {8, 5, 10, 11, 15}
A B = {............
AUB = {.....
(A B)' = {............
Verify: (AB)' = A' U B',
A' B' = {...............}
A'U B' = {............)
(AUB)' = {............
(A U B)' = A' B'​

Answer 1

AUB={1,11,13,8,5,10,15}

(AB)'={3,9,12}

A'B'={1,11,13}'{8,5,10,11,15}'

={3,5,8,9,10,12,15}{1,3,9,10,12,13}

={1,3,5,8,9,10,11,12,13,15}
