Question

Fie A={1;2;3;7} si B ={7;8} calculati A UB, B nA,A\B,B/A si alt ex. Se dau T ={6-1;6-2;6-3;6-4;} S={1+1;1+3;1+4;1+5;1+6} calculeaza S U T, T US,S nT,S-T si T-S ce observati desenati diagrame

Answer 1

a) A={1, 2, 3, 7}
B={7, 8}
A U B = {1, 2, 3, 7, 8}
B n A = {7}
A\B={1, 2, 3}
B\A={8}

b) T={5, 4, 3, 2}
S={2, 4, 5, 6, 7}
S U T = {2, 3, 4, 5, 6, 7}
T U S ={2, 3, 4, 5, 6, 7}
S n T ={2, 4, 5}
S\T={6, 7}
