Znajdź gdy:A ﮞ B, A ∩ B, A/B, B/A
a) A = { 1, 2, 3, 4, 5, 6 } B = {3, 5, 7, 9, 11 }
AUB = {1,2,3,4,5,6,7,9,11}
A∩B = {3,5}
A\B = { 1, 2, 4, 6 }
B\A = {7, 9, 11 }

b) A = { 2, 4, 6, 8, 10 } B = {x > 5 }
AUB = {2,4}U<5;+ ∞)
A∩B = {6,8,10}
A\B = {2,4}
B\A = <5;+ ∞)\{6,8,10}

c) A = B = ( 0; 7 )
d) A = { i x > 1 } B = { i }
dobrze przepisane?
