Question

Let Y be a random variable with probability distribution g(y). A graph of g(y) is given below: a. Is this a discrete or a continuous variable? Give a reason for your answer. b. Use the graph to show that g(y) is a density function. c. Use the graph in to calculate P(Y > 0.2). d. Give P(Y = 0.5). e. Derive F(y), the cdf of Y. f. Graph the cdf.
