Solution

The correct option is B $m \geq 0, n > 0, m \leq n$
Following two points are worth noticing while checking the relationship between m and n:
1. The probability of occurring of an event can never be more than one.
$H e n c e, P (E) = \frac{m}{n} \leq 1 \Rightarrow m \leq n$
And, 2. The number of events and the number of possible outcomes can never be negative. Thus, the value of m and n is always greater than 0.
$\Rightarrow m \geq 0, n > 0, m \leq n$
Thus, the correct option is B.
