Answer:
$21.25
Step-by-step explanation:
1. Convert the 15% to a decimal by dividing by 100. 15 ÷ 100 = 0.15
2. Multiply the $25 by the decimal of 15%. 25 × 0.15 = 3.75
3. Subtract your previous answer (3.75) from the original price of the game station. 25 - 3.75 = 21.75
4. Therefore the price of the game station after the discount is $21.75.

A simple question, but I decided to answer.
Good Luck!!
We have the following given
p1 - probability for outcome 1
p2 - probability for outcome 2
p3 - probability for outcome 3
v1 - amount of money that you will win or lose for outcome 1
v2 - amount of money that you will win or lose for outcome 2
v3 - amount of money that you will win or lose for outcome 3
Therefore,
p1v1 + p2v2 + p3v3 is the average money you win or lose in playing the game.
