Expert Answer
A = { 1,2,3,4,5 }
B = { 1,3,5,8 }
C = { 2,5,6,8 }
B ∪ C = { 1,2,3,5,6,8 }
A - [ B ∪ C ] = { 4 } ..........................(1)
----------------------------------
A - B = { 2 , 4 }
A - C = { 1, 3, 4 }
[ A - B] ∩ [ A - C ] = { 4 } .....................(3)
From eqn.(1) and eqn.(3), we get
A - [ B ∪ C ] = [ A - B] ∩ [ A - C ]
