Question

U = { 1,2,3,....,15 }
A = { 1,4,7,9,14 }
B = { 2,3,6,10,12,15 }

find A' and B'

Answer 1

A' = {2,3,5,6,8,10,11,12,13,15}
B' = {1,4,5,7,8,9,11,13,14}

Answer 2

To find A' = U / A
U / A = { 1,2,3,.....,15 } / { 1,4,7,9,14 }
A' = { 2,3,5,6,8,10,11,12,13,15 }

to find B' = U / B
U / B = { 1,2,3,.....,15 } / { 2,3,6,10,12,15 }
B' = { 1,4,5,7,8,9,11,13,14 }
