What is the chance you will play a dozen times?
What is the chance you will play no more than a dozen times?
Homework Answers
Probability of winning on a single play =1/38
1)
chance you will play a dozen times =P(lose in first 11 games and won on 12 th turn)
=(1-1/38)11*(1/38) =0.0196
2)
P( play no more than a dozen times ) =1-P(no win in first 12 games) =1-(37/38)12 =0.2739

Consider the strategy where you initially bet one euro and you keep playing and doubling your bet until the first time you win. At that point you go home, having made a net profit.
