Question

If A={x,y,z} then the number of non empty subsets of A is
a)-8
b)-5
c)-6
d)-7
What is the solution for this sum

Answer 1

$\underline{\bold{Answer :}}$

The set is A = {x, y, z}

We can get some sets using the elements x, y and z

They are

{x, y, z}, {x, y}, {y, z}, {z, x}, {x}, {y} and {z}

These all are subsets of A

Hence, we can get $\bold{7}$ non-empty subsets of A

Answer 2

Answer:

if A={x,y,z} then the number of non empty subsets of A is 7

Option d

Step-by-step explanation:

The number of non empty subsets is given by 2^m - 1

A={x,y,z}

⇒ m=3

number of non empty subsets = 2^m - 1 = 2^3 - 1

                                                  =  8 - 1

therefore the number of non empty subsets = 7

if A={x,y,z} then the number of non empty subsets of A is 7
