Using the expected value, it is found that a price of $6 should be charged to make it a fair game.
--------------------------
- The game is fair if the <u>expected value is 0</u>.
- The expected value is given by <u>each outcome multiplied by it's probability</u>.
- A probability is the <u>number of desired outcomes divided by the number of total outcomes</u>.
- In a standard deck, there are 52 cards.
- The cost of x.
- There are 4 Aces in a standard deck, thus
probability of earning 26 - x.
- There is 1 King of Hearts in a standard deck, thus
probability of earning 204 - x.
- There are 4 Jacks and 4 Queens in a standard deck, thus
probability of winning 13 - x.
- The other 39 cards you lose, thus
probability of losing x.
Considering we want the expected value to be 0.
$6 should be charged.

Answer:
- See below
Step-by-step explanation:
We can show that for x = 0, both sides of the inequality get the value of 1.
With x > 0, the left side goes towards - ∞ with the negative slope and the right side is always positive.
I'll give a graphical solution.
Hope this helps.
ANSWER:
m = -3/4
b = -3
STEP-BY-STEP EXPLANATION:
We have that the equation in its slope-intercept form is the following:
We calculate the slope as follows:
To calculate the slope we use the intercepts that are (-4, 0) and (0, -3), we replace:
Now, the value of b would be -3, since the y-intercept is (0,-3), therefore, the equation would be:
