11) Chevalier de Mere's Problem-
How many times must you throw two die in order to have half a chance of getting double sixes? (The original problem used the word dice but die is singular and dice is plural i.e., a pair of dice is two die.)
We know that (see attached). If you roll dice you have 36 outcomes. Also the probability of getting at least one double 6 on n rolls of the dice is the same as getting no double sixes on n rolls of a dice.
The probability of double sixes is 1/36. The probability of any combination other than double sixes is 35/36.
Thus, Pascal and Fermat concluded that solving for n in the formula below will solve the problem.
