Expert Solution

5 . p: Every prime number is odd.

Counter example, 2 is a prime and is even.

So, 2 is prime but not odd.

As it is false for at least one number, therefore 'p' is false.

6. Let ,A={a,b,c},B={0,1}

Now product of A and B is given by,

A×B={(a,0),(b,0),(c,0),(a,1),(b,1),(c,1)}

for ,10) you can re write no. 7 from 9

As it is the reverse of 7 to 9.

Hope you get it.

All solution.
