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.

(c)

a =  9

b =  48

c =

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

= 12  points

Step-by-step explanation:

Got it all from E D G E N U I T Y

Hope this helps ya'll :P

the answer to the question is a

step-by-step explanation:

it has the same slope and the same y-intercept.

y + 11 = -7/9(x - 18)

y + 11 =-7/9x + 14

b

y = -7/9x + 3

y-intercept (0, 3)
