any mathematician who has had something to do with probability??? it is really urgent.?

Answer 1

well, we cannot count Fermat, he is not a mathematician,its been said that Fermat is the greatest mathematician who wasn't a mathematician...Fermat was a Judge by profession and did mathematics to take his mind off of his cases.

I would say that one of the greatest Mathematicians who had something to do with probability is Blaise Pascal

Answer 2

The problem that inspired the development of mathematical probability in Renaissance Europe was the problem of points. It can be stated this way:
Two equally skilled players are interrupted while playing a game of chance for a certain amount of money. Given the score of the game at that point, how should the stakes be divided?

In this case 'equally skilled' indicates that each player started the game with an equal chance of winning, for whatever reason. For the sake of illustration, imagine the following scenario.

Pascal and Fermat are sitting in a cafe in Paris and decide, after many arduous hours discussing more difficult scenarios, to play the simplest of all games, flipping a coin. If the coin comes up heads, Fermat gets a point. If it comes up tails, Pascal gets a point. The first to get 10 points wins. Knowing that they'll just end up taking each other out to dinner anyway, they each ante up a generous 50 Francs, making the total pot worth 100. They are, of course, playing 'winner takes all'. But then a strange thing happens. Fermat is winning, 8 points to 7, when he receives an urgent message that a friend is sick, and he must rush to his home town of Toulouse. The carriage man who has delivered the message offers to take him, but only if they leave immediately. Of course Pascal understands, but later, in correspondence, the problem arises: how should the 100 Francs be divided?



In a letter to Pascal, Fermat proposes this solution:

Dearest Blaise,

As to the problem of how to divide the 100 Francs, I think I have found a solution that you will find to be fair. Seeing as I needed only two points to win the game, and you needed 3, I think we can establish that after four more tosses of the coin, the game would have been over. For, in those four tosses, if you did not get the necessary 3 points for your victory, this would imply that I had in fact gained the necessary 2 points for my victory. In a similar manner, if I had not achieved the necessary 2 points for my victory, this would imply that you had in fact achieved at least 3 points and had therefore won the game. Thus, I believe the following list of possible endings to the game is exhaustive. I have denoted 'heads' by an 'h', and tails by a 't.' I have starred the outcomes that indicate a win for myself.

h h h h * h h h t * h h t h * h h t t *
h t h h * h t h t * h t t h * h t t t
t h h h * t h h t * t h t h * t h t t
t t h h * t t h t t t t h t t t t

I think you will agree that all of these outcomes are equally likely. Thus I believe that we should divide the stakes by the ration 11:5 in my favor, that is, I should receive (11/16)*100 = 68.75 Francs, while you should receive 31.25 Francs.
I hope all is well in Paris,

Your friend and colleague,
Pierre

Answer 3

A Russian mathematician and a physician is the first person to use probability and he defined it as the number of favorable outcome divided by the number of possible outcome. He was considered as the "Father of the Theory of Probability".

And that's

infrom me if I'm not correct.
