Q5 of 71 Page 32

The number of subsets of the set {10, 11, 12} is

Given set A {10, 11, 12}


There are 3 elements in the set. ⇒ n(A) = 3


The number of subset for a set is given by n(p(A)) = 2m


Where m is the no. of elements.


So, no. of subsets = n(p(A)) = 23 = 8.


∴ option(B) is the correct answer.
