Answer:

NOTE: 1&3 ANSWERS IN ATTACHMENT  

Step-by-step explanation:

2. (i)  Given P={m,n} and Q={n,m} then  

P×Q={(m,n),(m,m),(n,n),(n,m)}

So, given value of P×Q is incorrect.

Hence, the given statement (i) is false.

(ii) If A and B are non-empty sets, then A×B is a non-empty set of ordered pairs (x,y) such that x∈A and y∈B

Hence, the given statement (ii) is true.
