4/24
Choice B is correct
Step-by-step explanation:
From the information given, there is 1 table for every 6 chairs at the restaurant. In ratio form this can be expressed as;
1:6
The ratio that is equivalent to this given ratio is 4/24. This can easily be checked through simplification of this ratio;
4/24; If we divide both the numerator and the denominator by 4 we obtain
1/6 which is equivalent to 1:6

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
