Question

Number of subsets in set A = {a, b, c} is ________​

Answer 1

Answer:

The list of all subsets of a,b,c is

= {a},{b},{c},{a,b},{a,c},{b,c},{a,b,c}

Step-by-step explanation:

Given A = {a, b, c}.

Then, n(A) = 3

The number of subsets = n[P(A)] = 2³ = 8

The number of proper subsets

= n[P(A)] – 1

= 2³ – 1

= 8 – 1

= Number of subsets in set A = {a, b, c} is _7_
