Let U be the universal set, where U=(1,2,3,4,5,6,7,8,9)let sets A and B. be subsets of U, whereA=(2,3,8,9) and B=(1,2,3,5)

Black_prince [1.1K]

(A U B) = {1, 2, 3, 5, 8, 9}

(A U B)^c = {4, 6, 7}

A^c = {1, 4, 5, 6, 7 }

B^c = {4, 6, 7, 8, 9}

A^c ∩ B^c = {4, 6, 7}

8 + 3(4 + 5)

8 + 3(9)

8 + 27 = 35
