Question 83888: Hi, can you help with this one:
Set X has x members and set Y has y members. Set Z consists of all members that are in either set X or set Y with the exception of the K common members (K > 0). Which of the following represents the number of members in set Z? The answer is x + y - 2K, but I don't understand why I should count K twice since it is the same members in both sets X and Y, I feel like it's duplicating the members, counting them out of set Z twice instead of just once. Thank you for your help.

Question 95657: I'm not sure where to start on this whole set and subset topic.
represent the following set using set-builder notation:
{0,2,4,...,12}
My teacher told me that three dots ... meant an infinate set, but looking at the problem more i would think the answer would be {0,2,4,6,8,10,12}
