Probability help!!!!!

Let A be the event $A=\{choosing \;an \;odd \;number\}$ and B be the vent $B=\{choosing \;an \;even \;number\}$ . Since the intersection of the events $A\cap B=\phi$ , the events A and B are mutually exclusive.

The number is either odd or even. Since $P(A)+P(B)=1$ , the events are mutually exclusive and exhaustive.

Correct choice is "the number is either odd or even".
