If there is a group of n people in a room, what is the probability that two or more of them having same
birthday? It is possible to determine answer to this question by simulation. (Hint: You can generate
random dates, n times and determine the fraction of people who born in a given day). Write a function
that determines the answer to this question by simulation. The program you write can take n as the
input and prints out the probability that two or more of n people will have the same birthday for
n=2,3,4…. 40

Problem 2 Part 1
Problem 2 Part 1
Develop the program, which accepts the gross pay and produces the amount of tax owed. For a gross pay of 100000 or less, the tax is 0%; for over 100000 and 300000 or less, the tax rate is 15%; and for any pay over 300000, the tax rate is 28%. Calculate tax pay and return the result to main method. Print the result in main method.

Write a program to print the pay slip for each employee. Your program must use the properties of object-oriented programming which are polymorphism and inheritance in constructing the classes for the employees. Your program must have a menu that gives the user an option whether to process the pay slip for part time or full time employee. For a part time employee, the input will be hours worked, hourly rate and sales achieved, and for full time employee, it will be overtime rate, overtime hours worked and sales achieved. Assume the basic pay for full time is $2000.
Below is the commission rate for the sales achieved.
$250 - $600 = 2%
$601 - $900 = 4%
Over $900 = 6%
Below is the commission rate for the sales achieved.
$250 - $600 = 2%
