Question

Fill in the blanks with element 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'={.......}
A union B={......}
(A intersection B)'={.......}

Answer 1

A'={3,5,8,9,10,12,15}
B'={1,3,4,9,12,13}
A union B= {1,3,4,5,8,9,10,12,13,15}
(A intersection B)' = { 1,3,4,5,8,9,10,12,13,15}
