(d) (e) Using the marginal density of Y from (b), find the probability that the walk-up window is in use between 1/4th and 3/4 of the time. 1 Are X and Y independent? Find the conditional density of Y given that the drive-up facility is in use 80% of the time, i.e. X = 0.8. (f) Use the conditional density found in part (e) to find that the walk-up facility is busy at most half the time given that X = 0.8.. (Hint: Integrate the density obtained in (e) over the required bounds)
