Question

From 1st lesson of mathematics part 1 (new syllabus) of commerce fyjc
A={C, O, L, E, G}
B={M, A, R, I, G, E}
C={L, U, G, A, E}
Then verify that A-(B union C) =(A-B) interest (A-C).

Answer 1

Answer:

A-(B U C) = A-{M, A, R, I, G, E, L, U}

={C, O}

( A-B) intersect (A-C) ={C,O,L }intersect{C,O}

={C,O}
