Question

Given U = {1, 2, 3, 4, 5, 6, 7, 8, 9}, A = {2, 4, 6, 8}, B = {1, 3, 4, 5, 7} C = {7, 8}
find: a. A ∩ B ____________________ b. B′ _____________________ c. A′ ∪ B′ ____________________ d. A – B _____________________ ​

Answer 1

Answer:

here is your answer

Step-by-step explanation:

A intersection B= (4)

B'={2,6,8,9}

A' union B'={9}

A-B={1,3,5,7}

Answer 2

Answer:

Step-by-step explanation:

a. A ∩ B =   { 4 }

b. B′ =   {2,6,8,9}

c. A′   B′ =  { 1 ,2,3,5,6,7,8,9}

d. A – B = {1,3,5,7}

e. (A ∩ C) ∩ (A   B) =   (A ∩ C)  = {8} , (A   B) ={1,2,3,4,5,6,7,8}

                                 (A ∩ C) ∩ (A   B) = {8}.
