Question

Sendo A= ( 1,2,3,4,5,), B=(3,4,5,6,7) e C= ( 5, 6, 7, 8, 9), Determine:

Answer 1

BUC=(3,4,5,6,7,8,9)
B∩C=(5,6,7)

Answer 2

A união B = ( 1,2,3,4,5,6,7 )

A união C = ( 1,2,3,4,5,6,7,8,9 )

B união C = ( 3,4,5,6,7,8,9 )

A intersecção B = ( 3,4,5 )

A intersecção C = ( 5 )

B intersecção C = ( 5,6,7 ).
