Question

PLEASE HELP ME SOMEONE! i DON'T KNOW WHAT TO DO!

Answer 1

(A∩B)´U C´

U= {1,2,3,4,5,67,8}

A={1,2,4,5}

B={2,3,5,6}

C= {4,5,6,7}

A ∩ B={2,5}

(A ∩B)´ = U -(A∩B)={1,2,3,4,5,67,8} - {2,5}={1,3,4,6,7,8}

C´= U - C={1,2,3,4,5,67,8} - {4,5,6,7}= {1,2,3,8}

(A∩B)´U C´={1,3,4,6,7,8} U {1,2,3,8}= {1,2,3,4,6,7,8}

paint numbers {1,2,3,4,6,7,8}
