Implement a utility class named Distribution, which contains the following two static methods.

a) The exponential method returns an exponential distribution value calculated with this formula, where mean is a double parameter which holds the distribution’s mean:
-Math.log(Math.random()) * mean

b) The normal method returns a normal distribution value calculated with this formula, where mean and deviation are double parameters that hold the distribution’s mean and standard deviation, respectively:
