QUESTION 21 The probability that a phone call will last less than t minutes can be approximated by the exponential probability function Probability that a call lasts less than 1 minute = 1-e-t/a a is the average call length e is Euler's number (2.71828) For example, assuming the average call length is 2 minutes, the probability that a call will last less than 1 minute is calculated as 1 e 1/2-0.3297 Using this probabilty equation, write a C++ program that calculates and displays a list of probabilties ot a call lsting less than 1 minute in 1-minute increments (2 points) Provide source code containing a comment with your name, course code and date (2 points) Also provide a screenshot of a run (2 points Submit source code and screenshot together in a zip file.
