If we have two sets A={4,4,4,3} & Set B={4,4,4,4}, what’s AUB?
Because we don’t count repeats right? So shouldn’t it be a case we consider? Or am I missing something?
According to my understanding, the question is using the same trick because when they specify number of elements repeats are not counted in the same. So, when they say 4 elements, they mean 4 different elements. It is the same logic you apply to get |S| for any set. You don’t count the repeats right. So, you can have a set like A= {2,3,4,5,5,5,5} and B= {1,1,1,2,3,4}. Total number of elements is still 4 each that is why your example wouldn’t make sense because there are only 2 elements in set A and 1 element in set B. It would be good to get a confirmation on my explanation though.

Actually that makes a lot of sense/ while we wait for a confirmation- thanks a ton! It makes a lot of sense, this really helped.

Your 2 sets could also look like this:
A: {1,2,3,4}
B: {1,2,3,4}
So, in this case, 4 is the minimum number of elements your set should have. Thereby, we are not counting repeats.
which is indeed the case - looks fine to me.
