Exercise 3 (30 points) A robot is deployed on Mars to study the presence of organic material. It is estimated that its lifespan T will follow the probabilistic law P(T t) = e^ t/4 This equation can be interpreted as saying that the probability that the robot will work at least T years is a decaying exponential. For instance, the probability that the robot will last one year or more is P(T 1) = e^ 1/4 = 0.779 The robot is deployed, and after four years it is still working. What is the probability that it will break at the end of the fourth year?
