1. In St. Louis, the average amount of rainfall in June is 4.3 inches (meaning the daily mean is 4.3/30 inches). On average, 20 days of June experience no rain at all (meaning the probability of 0 inches of rain on any June day is 20/30). Assume the pdf of inches of rainfall per day is exponential, so that the pdf has the form below. (a) Find a and b (so that E(X)-4.3/30) (b) What is the chance of getting...

Define the random variable Y = -2X. Determine the cumulativedistribution function (CDF) of Y . Make sure to completely specifythis function. Explain.Consider a random variable X with the following probability density function (PDF): s 2+2 if –2 < x < 2, fx(x) = { 0 otherwise. This random variable X is used in parts a, b, and c of this problem.
