1. (3 points, total) A discrete random variable has five possible outcomes with cumulative probabilities as shown in the following table: Outcome Probability (PD Cumulative Probability (CDF) -2 0.05 -1 0 1 0.15 0.6 0.75 1 (a) (1 point) Fill in the missing values in the column labeled Probability. (Please fill in table above.) (b) (1 point) What is the probability of getting a negative number? (c) (1 point) What is the expected value of this random variable? example PLACE ANSWERS IN THE GREEN CELLS. This applies to entire quiz. 5 18 23 You must show work to receive credit. Work could be as simple as coding your answer as in the box to the left as an Excel formula For example, if the question asked you to add up the values of cells G25, H25 and 125, you could write =sum(G25, H25, 125) in the answer cell and the correct answer of 46 would appear, but then I'd also be able to see the formula/equation that used, i.e. I'd be able to click into the answer cell and see "=sum(G25, H25, 125)" and that would be sufficient for your work.
