In a card game (using a standard deck of cards), you pay $5 to draw a single card. If you draw an Ace, you win $20. If you draw a face card, you win $10. If you draw a 2, you win $5.. . a) Fill in the probability distribution below:. . X51020. P(X) . . . b) What is the expected value?. c) Is the game fair? Why or why not?

Respuesta :

p$5 = 4/52 =1/13
p$10 = 16/52 =3/13
p$20 = 4/52 =1/13
now
expected value of x is the sum of x* P(x), 
which = 5/13 + 30/13 + 20/13
 = 55/13
hope it helps
