Calculate the number of subsets and the number of proper subsets for the set below.

M=x

We are asked to determine the number of subsets and the proper subsets of the set containing integers from 1 to 7. In this case, the sets should contain from 1 to 7 alone, pairs of numbers, triple combination of numbers and so on. The formula to be followed is 2^n - 1 equal to 2^7 - 1 equal to 127
