Problem 8. (Waiting Time) If X is the waiting time between now and the next event, the probability that X is greater than t is given by the exponential distribution P(X > t)-e-At, where the rate parameter is the average number of events per unit of time. Write a program waiting-time. py that takes two floats A and t as command-line arguments and writes the probability P(X > t python3 vaiting.time py 0.1 5 0.6065306597126334
