7.1.3 Probability of an event

Chapter 7: Probability

A long time ago…

Chevalier de Méré

One day, in 1654…

I would like to gamble today. Can’t wait to get more money..yeay!..of course I will win today

just like before..

Chevalier de Méré

…I should get at least one twelve in 24 rolls of two dice for me to win in this

game.Hmm..is it possible? I

should just make a try…

Chevalier de Méré

In the gambling place. After one hour..

Arghh..what a bad luck tonight. I have lost my money. How could it

be?..Better I ask Pascal before I get bankrupt.

Chevalier de Méré

He met Pascal to ask for solution..

My dear friend, Pascal. Could you help me..i’ve

lost much of my money..is it impossible

for me to get at least one twelve in 24 rolls of two

dice?

Ouh. Mere..Im so sorry.. from my calculation, I

think that you only have 49.1% to win this game.

But I didn’t know it is true or not. I cant confirm it. I will ask my friend to solve

this problem.

Blaise Pascal

Then, Pascal asked Fermat to find the solution together….

Fermat, my friend got problem in gambling. He did not know why his bet this time didn’t work as

before. Could we find the solution together?

Ouh..okay..we will find the solution together. I think to solve this problem, we have to use the concept called

probability. But no one had found the theory yet. So, why don’t we are the one

that discover it first..
