In the New York State Numbers Lottery, you pay $1 and can bet that the sum of the numbers that come up is 13. The probability of

Harman [31]

Answer:

The expected value of profit is -0.5125. This is expected loss as value is negative.

Step-by-step explanation:

We are given the following in the question:

P(winning) = 0.075

Thus,

P(Loosing) =

$1 - 0.075 = 0.925$

If we win we gain a profit of $5.50 and if we loose the lottery, we loose $1.

Thus, we can form the probability distribution in the following manner:

Event: Winning Loosing

Profit(x): +5.50 -1

P(x): 0.075 0.925

We have to calculate the expected value of the profit.

$E(X) = \displaystyle\sum x_i(P(x_i))\\E(x) = +5.50(0.075) + (-1)(0.925)\\E(x) = -0.5125$

Thus, the expected value of profit is -0.5125. This is expected loss as value is negative.

The cost of a large pizza is given by c = 0.50t + 18, where c is the total cost and t is the number of toppings. The cost of a m

Mashutka [201]

The toppings would still cost 0.50 each (since it is just toppings)

The large pizza costs $18 if you do not have any toppings
The medium costs half of the large

18/2 = 9

The medium costs $9 without any toppings, so your new equation will be:

c = 0.50t + 9

hope this helps
