##### Consider the Exponential distribution as model for the survival time of coronavirus on surfaces In experiments, it is often not feasible to run the study long enough that all the viruses die: For example, suppose that n viruses are each tested for a maximum of â‚¬ hours (C is called a "censoring time") The observed data are then as follows: k (where 0 < k < n) viruses died, al times V1, Vk= k viruses are still alive after time C . (a) If Y has an Exponential(0) , find P(Y >
