Find the number of subset and find the number of proper subsets of the set {31,3,16,25,8,19}
--------------------------------------------------------
This set has 6 elements.
Hence, the number of all its subset is  = 64, including the empty subset and the subset, which coincides 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 subsets is 62 =  .
It does not includes the empty subset and the subset, which coincides with the master set.
