1.	The total number of subsets of a finite set containing n elements is?(a) 2^n+1(b) 2n(c) 2^n(d) NThis question was addressed to me in an interview.I would like to ask this question from Subsets topic in division Sets of Mathematics – Class 11
Answer» Correct ANSWER is (c) 2^n The explanation: NUMBER of SUBSETS of a SET having r elements each is nCr. Hence, the total number of subsets is ^nC0 + ^nC1 + ^nC2 + ……+^nCn = 2^n.
