Consider two independent exponential random variables Y1 and Y2 that are exponentially distributed with mean 1 . Using Python, generate 106 different samples for each random variable. Using these samples: a. Estimate the average (mean) of Y3=Y1+Y2. b. Plot the complementary cumulative distribution (ccdf) of Y3. On the same figure, plot the ccdf of an exponential random variable with mean 2. What is your conclusion? Please provide the code used to obtain the answers to this question. Provide answers with 3 digits of precision
