Question

let A={1,2}and b{2,3}write down the following sets p(a)

Answer 1

Aloha user
________

A = { 1,2 }
B = { 2,3 }

we have got to find the power set ( A )

A = { 1,2 }

the total subsets which can be made are
${2}^{n}$
${2}^{2} = 4$

so 4 subsets can be made.
which are:

• {1}
• {1,2}
• {2}
• fie

the power set of A or p(A) = {{1},{1,2},{2},fie}
