The average lifespan for a certain type of vehicle is 8 years and follows an exponential distribution. A lot contains 200 of these vehicles, brand new. How many of the 200 would you expect to fail in their first 2 years? What is the approximate probability that 50 or more of them fail in their first 2 years? If you have learned that 30 vehicles have already failed in under 2 years, What is the approximate probability that no more than 10 of the rest of them fail in their first 2 years?
