For each of these scenarios you need to clearly define WHY it is the distribution you decided, including any assumptions, and give the answer both mathematically and via RStudio (include the R code). (a) A firm buys 500 identical components, whose failure times are independent and expo- nentially distributed with mean 100 hours. (i) Determine the probability that one component will survive at least 150 hours. (ii) What is the probability that at least 125 components will survive at least 150 hours? Show all working (even if you don't perform all of the calculations, show how it would be obtained by hand). Include two methods/distributions to do this method. Compare the methods and comment on any differences • the probability distributions for both (i) and (ii); • the assumptions you made to obtain these answers and for these to be a valid distribution; • the answer to the questions (both by hand and using RStudio).
