Question

Find the value of a and
If A = {1,2,3,4,5,6}then the number of proper sub sets is
a) 63
b) 36
c) 64
d) 25
GRY<5 Then AB​

Answer 1

Step-by-step explanation:

we know that the number of proper sub sets of a set with 'n' elements is (2 power n) - 1

Given, A = {1,2,3,4,5,6}

=> n = 6

.•. number of proper sub sets = 2^6 - 1 = 64-1 = 63

Answer 2

Answer:

Rule for subset = 2ⁿ

Where n is

A= {0,1,2,3,4……n}

As there are 6 elements in A than the no of subsets of A must be

= 2^6= 64

As for proper subset

A subset it self is not counted so eliminate it

Proper subset of A=64–1=63
