Hi I need help with this problem I have some trouble with partitions:
The context is Discrete math /relation
Which of these collections of subsets are partitions of the set of integers?
1- The set of even integer and the set of odd integers.
2- the set of positive integer and the set of negative integers.
3- the set of integers divisible by 3, the set of integers leaving a remainder of 1 when divided by 3, and the set of integers divisible by 3, the set of integers leaving a remainder of 2 when divided by 3.
4- The set of integers less than -100, the set of integers with absolute value not exceeding 100, and the set of integers greater than 100.
5- the set of integers not divisible by 3, the set of even integers and the set of integer that leave a remainder of 3 when divided by 6.
Are my answers correct?
I found yes for all cases . but I am suspicious.
Thank you for your help
