Answer:
Step-by-step explanation:
You need to analize the information given in the exercise.
In this case you know that the List price is:
And, based on the data given, you also know that the Trade discount is:
Then, the first step you need to apply is to multiply the List price by the Trade discount, as you can observe below:
Now it is important to remember that, by definition, the Net cost can be found by subtracting the List price (which in this case is $74.13) and the product of the List price and the Trade discount (which in this case is $24.71).
Then, through this procedure, you get the following Net cost:
Answer:
Expected value = $8.89
Step-by-step explanation:
cost of playing game = $1
winning if sum is odd = $10
winning if sum is 4 or 8 = $5
winning if sum is 2 or 12 = $50
two dice rolled, possible outcomes =
(1,1) (1,2) (1,3) (1,4) (1,5) (1,6)
(2,1) (2,2) (2,3) (2,4) (2,5) (2,6)
(3,1) (3,2) (3,3) (3,4) (3,5) (3,6)
(4,1) (4,2) (4,3) (4,4) (4,5) (4,6)
(5,1) (5,2) (5,3) (5,4) (5,5) (5,6)
(6,1) (6,2) (6,3) (6,4) (6,5) (6,6)
total no. of outcomes = 36
now according to the table of outcome with respect to winning money, we can calculate expected value by multiplying the probability of each roll with winning amount associated with each roll. and subtract the amount that we paid for the game that is $1.
E(x) = 1/36*($50) + 1/18*($10) + 1/12*($5) + 1/9*($10) + 5/36*($0) + 1/6*($10) + 5/36*($5) + 1/9*($10) + 1/12*($0) + 1/18*($10) + 1/36*($50)
= 25/18 + 5/9 + 5/12 + 10/9 + 0 + 5/3 + 25/36 + 10/9 + 0 + 5/9 + 25/18
Expected value = $8.89
Subtract the amount that was paid to play the game that is $1.
$8.89 - $1 = $7.89
A profit of $7.89 is expected every-time the game is played.
