Answer:
I think the answer would be 0.2
Step-by-step explanation:
Given:
A fair die is rolled.
It pays off $10 for 6, $7 for a 5, $4 for a 4 and no payoff otherwise.
To find:
The expected winning for this game.
Solution:
If a die is rolled then the possible outcomes are 1, 2, 3, 4, 5, 6.
The probability of getting a 6 is:
![P(6)=\dfrac{1}{6}](https://tex.z-dn.net/?f=P%286%29%3D%5Cdfrac%7B1%7D%7B6%7D)
The probability of getting a 5 is:
![P(5)=\dfrac{1}{6}](https://tex.z-dn.net/?f=P%285%29%3D%5Cdfrac%7B1%7D%7B6%7D)
The probability of getting a 4 is:
![P(4)=\dfrac{1}{6}](https://tex.z-dn.net/?f=P%284%29%3D%5Cdfrac%7B1%7D%7B6%7D)
The probability of getting other numbers (1,2,3) is:
![P(\text{Otherwise})=\dfrac{3}{6}](https://tex.z-dn.net/?f=P%28%5Ctext%7BOtherwise%7D%29%3D%5Cdfrac%7B3%7D%7B6%7D)
![P(\text{Otherwise})=\dfrac{1}{2}](https://tex.z-dn.net/?f=P%28%5Ctext%7BOtherwise%7D%29%3D%5Cdfrac%7B1%7D%7B2%7D)
We need to find the sum of product of payoff and their corresponding probabilities to find the expected winning for this game.
Therefore, the expected winnings for this game are $3.50.
Answer:
68
Step-by-step explanation:
derive that 25 percent of 68 equals 17.
Answer:
Answer to the question is A
Answer:
x = 6/4 or 1 1/2
Step-by-step explanation:
4x+3=9
Subtract the 3 from both sides
4x+3=9
-3 -3
4x = 6
Divide both sides by 4
x = 6/4 or 1 1/2
