(Edit: Video maker helped in reply!) Horrible examples, I'm sorry. I keep finding info from different sources saying that a sequence with {1,4,4,4,6} has a cardinality of 5 and others saying it has a cardinality of 3, but the vaaast majority show examples with NO repeating values, which destroys any attempt to figure this out.
The set {1,4,4,4,6} has a cardinality of 3. To further clarify, the cardinality of a set is the number of distinct elements the set contains. By definition a set is a collection of unique items, since {1,4,4,4,6} contains repeats the set should be written as {1,4,6} which we can clearly see has a cardinality of 3. Hope this helps!
I love the way you teach
This helped a lot during lockdown!
Thanks 🎉

@@MathsByAli Thank you so much! I was getting frustrated looking at 20 sources with no one explaining this, thank you!
