finite and infinite sets
A finite set is a set that has numbers you can count. Its not like infinite with no end it has an end.
Finite, countably infinite and uncountably infinite.
A finite set is one containing a finite number of distinct elements. The elements can be put into a 1-to-1 relationship with a proper subset of counting numbers. An infinite set is one which contains an infinite number of elements.
One possible classification is finite, countably infinite and uncountably infinite.
Sets are collection of distinct objects. In mathematics there are different types of sets like Finite set, Infinite set, Universal set, subset, equal set, equivalent set. Example of Finite set {1,2,3,4}. Infinite set:{1,2,3....}.
The set of your friends is finite. The set of counting numbers (part of which you will use to count your friends) is infinite.
