Answer:
E(Y) = $0.5
Var(Y) = 14.25
you should pay the same amount $0.5
Step-by-step explanation:
E(Y) = = Σ(YP)
P = probability of each outcomes.
Var(Y) = Σ
p − (μ x μ)
E(Y) = (2 x 0.25) +(6 x 0.25) + (0.5 x (-3)) = $0.5
Var(Y) = (
x 0.25) + (
x 0.25) +(
x 0.5) - (
)
= 14.5 - 0.25
Var(Y) = 14.25
for the difference between the payoff and cost of playing to have mean 0, you should pay the same amount $0.5

The first option is correct.
Answer: can you take a closer picture
Step-by-step explanation:
yes and no answer+the math:
1) yes
2) yes
1) so if you take 255-75 you get 180 now keep that in mind for number 2, when you divide 180 by 6 you will get 30 so we can give 30 cards to everyone
2) remember the 180? were using it again. if you do 180 and divide that by 4 you get 45 so we can give 45 cards to everyone.
hope this helps!
