Answer:
[tex]Proper\ Subset = 63[/tex]
Step-by-step explanation:
Given
[tex]N = \{10, 50, 63, 15, 40, 55\}[/tex]
Required
Determine the proper subsets
This is calculated by:
[tex]Proper\ Subset = 2^n - 1[/tex]
Where n is the number of elements in the set.
In this case,
[tex]n = 6[/tex]
So:
[tex]Proper\ Subset = 2^n - 1[/tex]
[tex]Proper\ Subset = 2^6 - 1[/tex]
[tex]Proper\ Subset = 64- 1[/tex]
[tex]Proper\ Subset = 63[/tex]
