An urn includes white and black balls. if a random sample of length is chosen, the probability that it consists of exactly white balls: 
Sample area = M + N
we are choosing r balls from the pattern space
So the possibility of having the exactly white ball is ok which means the okay of decided on balls is black
So the probability is
Probability is honestly how probable something is to manifest. each time we are unsure about the final results of an event, we will talk about the probabilities of certain results—how in all likelihood they're. The analysis of activities governed via probability is referred to as information.
Probability is the branch of mathematics concerning numerical descriptions of ways in all likelihood an occasion is to occur, or how in all likelihood it's miles that a proposition is proper. The opportunity of an occasion is more than a few between zero and 1, in which, more or less talking, 0 suggests the impossibility of the occasion and 1 shows reality.
Probability = the number of methods of achieving achievement. the full number of feasible effects. for instance, the possibility of flipping a coin and it being heads is ½, due to the fact there may be 1 manner of getting a head and the whole wide variety of viable consequences is two (a head or tail).
