Question

Show in at least two different ways that the sets A-(BnC) and(A-B)U(A-C) are equal

Answer 1

Well do you know you can use a truth table to show the equality of those two sets? Or you can just prove the sets are equal by using a non-truth table method...just using the definitions of the sets...which kinda seems similar to me.

Answer 2

Ok I know that I have to do with truth table but how? I do not know the way...If it is possible can you show me the solution pleeeeaaasee I really need you help

Answer 3

A-B
means in A but not in B
so you translate that to A and not B

AUB
means A or B or both

Answer 4

maybe you can try it now given the definitions of those

Answer 5

Ok thnx a lot...
