Question

find the number of subsets & the number of proper subsets of a sets A={x,y,z,p,q}
​

Answer 1

Answer:

Step-by-step explanation:

no of subsets  = $2^n$

n is number of terms in the set

$2^n = 2^5$

    $= 2$ × $2$ ×

    $= 32$

no of proper subsets = $2^n - 1$

$2^n = 2^5 - 1$

    $= 32 - 1$

    $= 31$

Here for proper subsets -1 is there because a set is also a subset of itself but not a proper subset of itself
