(you do not need to find the cdf. only write the program.)

Calamity Jane goes to the bank to make a withdrawal, and is equally likely to find 0 or 1 customers ahead of her. The service time of the customer ahead, if present, is exponentially distributed with parameter lambda. What is the CDF of Jane's waiting time?

Write programs java or python to simulate the problem above and display the output in a graphical form, with the following simplifications:

Repeat the program with lambda = 1, 10, 30, 60
