# Let X = { a , b , c } . Recall that P ( X ) is the power set X. Define a relation S P ( X ) as follows: For all sets A and B in P ( X ) , Is { a , b } S { b , c } ? Is { a } S { a , b } ? Is { c } S { b } ?

To determine

(a)

Find out whether {a, b} S {b, c} or not

Explanation

Given information:

Let X = {a, b, c}.

Define a relation SonP (X) as follows:

For all A, BP(X),A SBA has the same number of elements as B.

Calculation:

X={a,b,c}A S BA has the same number of elements as B

To determine

(b)

Find out whether {a}S{a, b} or not.

To determine

(c)

Find out whether {c}S{b} or not.
