Question

Let U= {1, 2, 3, 4, 5, 6, 7, 8, 9, 10}
A = {1, 2, 4, 6, 8, 10}
B = {1,3,5,7,8,9}
Find (a) A' (b) B' (c) A'UB' (d) A' B' (e) (AUB)'. Also show (AUB)' =A'B'..​

Answer 1

Answer:

a) A' = U - A = { 3,5,7,9}

b) B' = U - B = { 2,4,6,8,10}

c) A' U B' = { 2,3,4,5,6,7,8,9,10}

d) A' B' = fie

e) (AUB)' = fie

so they are equal
