The correct statement for the probability distribution is
There are 'm' number of favourable eases to event A and 'n' are non-favourable eases, both are equally likely and mutally exclusive, the probability of occurring the event A is $$P\left( A \right) = \frac{m}{{m + n}}.$$   This formula corresponds to which one of the following approaches to probability?
