You pick a card at random from an ordinary deck of 52 cards. If the card is an ace, you get 9 points; if not, you lose 1 point. 2 lines connect and go up to the right and down to the right. The line that goes up to the right points to Ace, and the line that goes down to the right points to Not an ace.

What is the expected value? Should you play the game?  

✔ –3/13 points; no, you should not play the game

For what expected value is a game fair?

✔ E(X) = 0

What value for the aces would make the game fair? To find this, solve the equation:

0 = 4

$450

step-by-step explanation:

first, you have to multiply 150x2=300

next, you have to add 150+300= 450

sinn is the total amount of students now and m were the students before, you subtract them both (n-m) and divide that by m. then, since to get a percentage from a fraction you have to multiply by 100, your answer should look like this: n-m/m*100
