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 $Y^{2}$ p − (μ x μ)

E(Y) = (2 x 0.25) +(6 x 0.25) + (0.5 x (-3)) = $0.5

Var(Y) = ( $2^{2}\\$ x 0.25) + ( $6^{2}$ x 0.25) +( $-3^{2}$ x 0.5) - ( $0.5^{2}$ )

= 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
