Answer:
a.
chance you win.
b. The expected value of the game is -$2.08.
Step-by-step explanation:
A probability is the number of desired outcomes divided by the number of total outcomes.
You roll 2 die and if you toss 2 sixes
For each roll, 6 possible values, 1 of which is 6. So the probability of rolling two sixes is:
![p = (\frac{1}{6})^2 = \frac{1}{36}](https://tex.z-dn.net/?f=p%20%3D%20%28%5Cfrac%7B1%7D%7B6%7D%29%5E2%20%3D%20%5Cfrac%7B1%7D%7B36%7D)
a. What is the chance you win?
chance you win.
b. What is the expected value of the game?
1/36 probability of winning 100.
35/36 probability of losing 5. So
![E = \frac{1}{36}*100 - \frac{35}{36}*5 = \frac{100 - 175}{36} = -\frac{75}{36} = -2.08](https://tex.z-dn.net/?f=E%20%3D%20%5Cfrac%7B1%7D%7B36%7D%2A100%20-%20%5Cfrac%7B35%7D%7B36%7D%2A5%20%3D%20%5Cfrac%7B100%20-%20175%7D%7B36%7D%20%3D%20-%5Cfrac%7B75%7D%7B36%7D%20%3D%20-2.08)
The expected value of the game is -$2.08.
