There are three sets:

A = { 1, 2, 3, 4 }

B = { 3, 5, 6, 7 }

C = { 1, 3, 7, 8 }

Find:

(A⋃ B)⋂ C

Hello,

Just write (A⋃ B), which will be composed of all elements of A and all elements of B.

x € A⋃B means that x is in A OR in B (non-exclusive or, so it can be in A and B)

Then, (A⋃ B)⋂ C will be any elements which are in (A⋃ B) AND in C. - March 16th 2008, 02:54 AMjanvdl
