Question

3. How many subsets can you form in the given set A = {k, e, y}?

A. 6
C. 8
B. 7
D. 9

Answer 1

answer=C

Explanation:

number of elements in A=3

so, n=3

number of subsets=
`2^(n)`, where n the number of elements in A.

=
`2^(3)`=8 subsets

the subsets of A are,

Ф,

{k},{e},{y},

{k,e},{k,y},{e,y},

{k,e,y}
