Question

Let's= {1,2,3,4,5,6}. Find the number of subset of s having 1,2​

Answer 1

Answer:

4

Step-by-step explanation:

Given :-

U = {1,2,3,4,5,6}

S = {1,2}

We know that,

$P(S) = {2}^{n}$

$\implies \: {2}^{2}$

$\implies \: 4$

Hence it will have 4 subsets, They are

P(S) = {ϕ, {1},{2},{1,2}}
