Acontractor has submitted bids on three state jobs: an office building, a theater, and a parking garage. state rules do not allow a contractor to be offered more than one of these jobs. if this contractor is awarded any of these jobs, the profits earned from these contracts are: million from the office building, million from the theater, and million from the parking garage. his profit is zero if he gets no contract. the contractor estimates that the probabilities of getting the office building contract, the theater contract, the parking garage contract, or nothing are , , , and , respectively. let be the random variable that represents the contractor's profits in millions of dollars. write the probability distribution of . find the mean and standard deviation of .

8

step-by-step explanation:

this is a subtraction problem.

10 - 2 = 8

to plot points   for x just start at the origin (middle) and go to the left however many times it say(if the number is a positive) if the number is a negative then go right however many times it says if it is 0 go nowhere

now keep you pencil there and go up however many times it says on y(if it is positive) if it is negative then go down however many times it says. if it says 0 go nowhere.

you have just plotted a point! now when you finish plotting all of them connect them with a ruler

plot each point as (-3, 7), (0,4), (3,1), (8,-4)   in the parenthesis on the left of the comma is x and the right is y.

do i do it on a graph?
