Hi, in the course video greg has written that - “a set does NOT count repeats” but it should be “a set does not ALLOW repeat” since allowing v/s counting are different things. we can allow repeats but not count them as separate.
which is what Greg suggests in the example that {1,1,1,1,1} = {1} are the SAME sets.
but then I found this below question 5 in the " PrepSwift Quant Tickbox Quiz #14 (Data Analysis Column 2)" which says that in sets repeats are not “allowed”
so what is it exactly?
are the repeats allowed but not counted as screenshot 1 suggests?
or are repeats not even allowed as below screenshot suggests?
