Answer:
k = 13
Step-by-step explanation:
Given
= 4
Multiply both sides by 3.25 to clear the fraction
k = 4 × 3.25 = 13
Using the expected value of a discrete distribution, it is found that the amount of points the player should lose for not rolling doubles in order to make this a fair game is of 1.
<h3>What is the expected value of a discrete distribution?</h3>
The expected value of a discrete distribution is given by the <u>sum of each outcome multiplied by it's respective probability</u>.
In this problem, considering 6 out of 6^2 = 36 outcomes are doubles, we have that the distribution is:
P(X = 5) = 1/6.
P(X = x) = 5/6.
A fair game means that the expected value is of 0, hence:
The amount of points the player should lose for not rolling doubles in order to make this a fair game is of 1.

Answer:
sorry need some points
Step-by-step explanation:
49 + 710 is 10390.49 + 710 is 10390.
A) $200.87
231------------------115%
X-----------------------100%
115x = 231x100
115x = 23100
Divide both sides by 115
X= 200.86956523
X= 200.87
