WebDefinition: If a set contains no element or a definite number of elements, it is called a finite set. If the set is non-empty, it is called a non-empty finite set. Some examples of finite sets are: A = {x : x is a month in a year}; Set A will have 12 elements. B= {y: y is the zero of a polynomial x 4 -6x 2 + x+ 2}; Set B will have 4 zeroes.
