Question

List are the subsets of the set D = {a,b,c,d}​

Answer 1

Step-by-step explanation:

Here is your answer:

={{ϕ} ,{a},{b},{c},{d},{a,b},{a,c},{a,d},{b,c},{b,d},{c,d},{a,b,c},{a,b,d},{a,c,d},{b,c,d},{a,b,c,d}

See this is the correct way to understand

since {a,b,c,d} contains four so total number of subsets are calculated as power of 2 like this

=(2)⁴

=16

Therefore , so there are total 16 subsets.
