When two sets have the same and equal elements, they are called Equal Sets.
An Equivalent Set is simply a set with an equal number of elements. The sets do not have to have the same exact elements, just the same number of elements.
Cardinality Set is basically the size of the set.
Subset is a set of which all the elements are contained in another set.
Answers & Comments
Give one example of the following kinds of sets.
Equal Sets:
Set A = {1, 2, 3, 4, 5}
Set B = {1, 2, 3, 4, 5}
Equivalent Sets:
Set C: {Sweater, Mittens, Scarf, Jacket}
Set D: {Apples, Bananas, Peaches, Grapes}
Cardinality Of Set:
|A| = 4
A= {1,4,6,7}
Subset:
A = {1, 2, 3} is a subset of B = {1, 2, 3, 4, 10}
