2. Develop a Python application that chooses n random numbers between 1 and 30 and determines the average. Repeat this experiment several times using a larger n each time, and finally plot a graph. You need to perform the following tasks. Submit your codes and screenshot of the graph were required

a) Pick a random number between 1 and 30 and find the average.

b) Pick three random numbers between 1 and 20 and find their average.

c) Pick three random numbers between 1 and 30 and find their average.

d) Pick 15,000 random numbers between 1 and 10 and find their average.

e) Plot the results using a Graph (Matplotlib)
