Here is the complete question:

Test for the commutative property of union and intersection of the sets  

P = { x : x is a real number between 2 and 7} and  

Q = { x : x is an irrational number between 2 and 7}.

Answer:

P = {x : x is a real number between 2 & 7}

Q = {x : x is an irrational no.between 2 & 7}

We know that P contains all the rational numbers between 2 and 7.

And PUQ and QUP each of them contain all the real numbers which are between 2 and 7.

Here Q is the proper subset of P

PnQ = QnP = Q
