Question

A= (1,2,3,4,7,11,12,15)
B= (0,1,2,7,6,5,3,10,21)
Calculati: A∪B,A∩B,A/B,B/A

Answer 1

[tex]A= \Big\{1,2,3,4,7,11,12,15\Big\}\\ \\ B = \Big\{0,1,2,7,6,5,3,10,21\Big\}\\ \\ \\ A\cup B = \Big\{0,1,2,3,4,5,6,7,10,11,12,15,21\Big\}\\ \\ A\cap B = \Big\{1,2,3,7\Big\} \\ \\ A\backslash B = \Big\{4,11,12,15\Big\}\\ \\ B\backslash A = \Big\{0,5,6,10,21\Big\}[/tex]
