Question

Set of letters of English alphabet is__________________

(a) empty set

(b) singleton set

(c) finite set

(d) infinite set

This question was addressed to me during an interview.

This intriguing question comes from Finite and Infinite Sets in division Sets of Mathematics – Class 11

Answer 1

Right option is (c) finite set

To explain I would say: Set of letters of English alphabet has 26 elements so it is a finite set.

It is not a singleton, empty or infinite set. Empty set has no element, singleton set has one element, infinite set has infinite number of elements.
