Question

For problems 9 - 28, find the indicate using this information: U-1, 2, 3, 4, 5,6, 7, 8, 9,101 A-, 2, 5, 6, 9, 101 B-13, 4,7, 8] C-[2, 3, 8, 9,101 26. Bn(cna)

For my statistics class. I am not sure if I am supposed to multiply the B intersection with what is in parenthesis. Thank you in advance!

Answer 1

U={1,2,3,4,5,6,7,8,9,10}

A={1,2,5,6,9,10}

A'={3,4,7,8}

B={3,4,7,8}

C={2,3,8,9,10}

C $\cap$ A`={2,3,8,9,10} $\cap$ {3,4,7,8}

={3,8}

(C $\cap$ A`)`={1,2,3,4,5,6,7,8,9,10} - {3,8}

={1,2,4,5,6,7,9,10}

B $\cap$(C $\cap$ A`)`={3,4,7,8} $\cap$ {1,2,4,5,6,7,9,10}

={4,7}
