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={.........}
(A intersection B)'={.......}

Answer 1

Step-by-step explanation:

•A'= {3,5,8,9,10,12,15}

•B'={1,3,9,12,13}

•AUB = {1,3,5,8,9,10,13,15}

•A interaction B = {3,9,12}

•(A intention B)' = {1,5,8,10,11,13,15}

Answer 2

Given : U = { 1 3 5 8 9 10 11 12 13 15}

A = { 1 11 13}

B = { 5 8 10 11 15}

To Find : A' , B'   (An B) ( AnB)' , ( AUB)​

Solution:

A' = U - A

A'  = {   3 5 8 9 10  12   15}

B' = U - B

B' = {  1 3   9  12 13  }

( AUB)​ =  {  1 5 8 10 11   13   15 }

(A n B) = ( A ∩ B) = { 11}

( AnB)' = ( A ∩ B)'

= U -  ( A ∩ B)

A ∩ B  = { 11}

( AnB)' = ( A ∩ B)'  =  { 1 3 5 8 9 10 12 13 15}
