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](https://tex.z-dn.net/?f=1%20-%200.075%20%3D%200.925)
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](https://tex.z-dn.net/?f=E%28X%29%20%3D%20%5Cdisplaystyle%5Csum%20x_i%28P%28x_i%29%29%5C%5CE%28x%29%20%3D%20%2B5.50%280.075%29%20%2B%20%28-1%29%280.925%29%5C%5CE%28x%29%20%3D%20-0.5125)
Thus, the expected value of profit is -0.5125. This is expected loss as value is negative.

Answer:
x axis
Step-by-step explanation:
We know the x value stays the same. If you were to graph the line y=3 and y=-3, you would see that it is a reflection over the x axis.
