Suppose you want to play a carnival game that costs 4 dollars each time you play. If you win, you get $100. The probability of winning is 1⁄100. What is the expected value of the amount the carnival stands to gain?

The answer is: -3

Step-by-step explanation:

The expected value is given by adding the values of posible gain mutiplied by the probability of getting that gain so you lose the $4 you pay to play the game with probability 1-1/100=99/100 and you gain 100-4=96 dollars if you win with probability 1/100, so

check above link.

graphically?   well, you graph them both, the solutions is where they both intersect each other, since there are two solutions, meaning they will meet twice, or namely the linear will run into the quadratic curve twice, and where they meet, those x,y coordinates are the solutions to the system.
