If A is the set of even integers and B the set of integers which are multiples of 3, describe the set (AUB) - (AnB) ? Basically the answer only requires words, no Venn diagram or the lot. So I just put in words .... it's the set which comprises of the even integers OR the odd integer which a multiples of 3 but not both. or should I say... it's the set of even integers and multiples of three minus the set of even multiples of three. Which is the correct answer please anyone?
