# Math Help - Statistics...probability model

1. ## Statistics...probability model

I need to create a probability model for the amount I win at this game.

How would I set this up?

You roll a die. If it comes up a 6, you win $100. If not, you get to roll again. If you get a 6 the second time, you win$50. If not, you lose.

Id really appreciate it if someone could help me!

Pr(Win $100) = 1/6. Pr(Win$50) = (5/6)(1/6) = 5/36.
Pr(You lose) = 1 - (1/6) - (5/36) = 25/36.
