Question: Suppose that the elapsed time, in years, until the next car accident at Broad Avenue and Esplanade Avenue follows an exponential distribution with parameter

Suppose that the elapsed time, in years, until the next car accident at Broad Avenue and Esplanade Avenue follows an exponential distribution with parameter A = 3. (This means that the expected value of time until next car accident is 1/3 years). Use the linearity of expectation to answer the following questions, indicating how linearity of expectation applies in each case. (a) What is the expected value of elapsed time until the next car accident, measured in days? (b) What is the expected value of "time until the sixth car accident"?
