find the number of proper subsets of the set {29, 2, 13, 27, 10, 21} ?
----------------------------------------------------------------------
The given set contains 6 elements.
Hence, it has  = 64 subsets including the empty subset and the subset coinciding with the master set.
See the lesson How many subsets are there in a given finite set of n elements? in this site.
The number of proper subset is 64-2 = 62.
It does not include the empty subset and the subset coinciding with the master set.
