The general formula for number of subsets is 2%5En and the number of proper subsets is 2%5En+-+1, where n is the number of elements.

if given set { .11, 14, 17, 2.}, we can see that the number of elements is n=4
so, the number of subsets is
2%5En=2%5E4=16
and the number of proper subsets is
2%5En+-+1=2%5E4+-+1=16-1=15
