If A is an event, then probability that A will occur is given by

P(A)= no. of favorable outcomes / total no. of possible outcomes

Is this just a definition, or is there some special significance in taking the number of favorable outcomes as the numerator and total no. of possible outcomes as the denominator? Is it because since the numerator will always be less than the denominator, it will be easier to work with the ratio?
