For the universal set U= {0,1,2,3,4,5,6,7}

And the sets A={1,5}, B={1,2,3,4}

And C= {4, 6} lists the elements in the following

Sets.

a. A ¢¯ B

b. A U Bf

c. A ¢¯(B U C)

d. C ¢¯ (B ¢¯ A)f

U means: state all elements that you find in either one set OR the other

¡û means: state all elements that you find in both one set AND the other

so let's do c)

A ¡û (B U C)

= A ¡û {1,2,3,4,6}

= {1,5} ¡û {1,2,3,4,6}

={1}

U means: state all elements that you find in either one set OR the other

¡û means: state all elements that you find in both one set AND the other

so let's do c)

A ¡û (B U C)

= A ¡û {1,2,3,4,6}

= {1,5} ¡û {1,2,3,4,6}

={1}

Do i have a correct. {1, 5}

I do not get D. can you explain it to me?
