Question

Total number of proper subsets of a set A={x: x is a vowel}​

Answer 1

Answer:We see, in the word 'MATHEMATICS' there are 3 vowels viz. a,e & i. So, the set of the vowels [= {a,e,i} ] consists of 3 elements. Hence, no. of subsets is = 2^3 = 8.

Therefore, no. of proper subsets would be,

= (8–1) = 7.
