A person creates a game in which a person pays $5.00 to play. Then, they draw a single card from a standard shuffled deck of car
ds.
If they draw a face card, they win $10.00 (i.e. they get their $5.00 back and get an extra $5.00).
If they draw an ace, they win $20.00 (i.e. they get their $5.00 back and get an extra $15.00).
With any other draw they lose their money.
What is the expected money value playing this game?
-$5.00
-$1.15
$1.31
$0.38

Answer:
(g-f) (-1)= sqrt(15)
(f/g)(-1)= 0
(g+f)(2)=sqrt(3)-3
(g*f)(2)=-3*sqrt(3)
Step-by-step explanation:
We have to eval the expressions given in the point indicated.
Lets start by the first equation
(g-f)(-1)= g(-1) - f(-1)= =
Now, lest continue with the others
(f/g)(-1)= f(-1)/g(-1)= (1-1)/sqrt(15)=0
(g+f)(2)=g(2)+f(2)=sqrt(3)-3
(g*f)(2)=g(2)*f(2)=sqrt(3)*(-3)=-3sqrt(3)
