Question

Can anyone please answer this for me! im really bad at math

Let U = {0,1,2,3,4,5,6,7,8,9} C= {x| x is prime}
A= {0,1} D= {x| x is a divisor of 8}
B= {x| x is odd} E= {x| x is a multiple of 3}

1. List the elements of B, C, D, and E.

2. Find
(a) B U C U D
(b) (B U C U D)’
(c) A’ U C’
(d) (D U E ) ∩ C
(e) A ∩ ( B U D )’
(f) A U B U C U D U E
(g) (B ∩ E)‘
(h) A x D
(i) ( A U B U C U D U E)‘
(j) (D ∩ E)

Answer 1

Answer:

1.Elements

B={1,3,5,7,9}

C={2,3,5,7}

D={1,2,4,8}

E={3,6,9}

2.Find

a, B U C U D={ }

b, B U C U D)’={1,2,3,4,5,,7,8,9}

Step-by-step explanation:

Elements:

U = {0,1,2,3,4,5,6,7,8,9}

C={2,3,5,7}(1 is not prime number)

A={0,1}

D={1,2,4,8}(divisors of 8)

B={1,3,5,7,9}(odd numbers)

E={3,6,9}(multiple of 3)

Find:

a, B U C U D={1,3,5,7,9}U{2,3,5,7}U{1,2,4,8}

              ={ } (Null Set(No Common Element))

In "a" check if you are missing any brackets().

b,  (B U C U D)’={1,2,3,4,5,,7,8,9}(Compliment)

B U C U D is like the opposite of (B U C U D)’

In B U C U D there was no Common Element so in (B U C U D)’  we have to bring in every element in B,C and D.
