A class consists of 3 students from Ashville and 4 from Bewton. A committee of 5 students is

chosen at random the class.a. Find the number of committees that include 2 students from Ashville and 3 from Bewton

are chosen.

b. In fact 2 students, from Ashville and 3 from Bewton are chosen. In order to watch a video,

all 5 committee members sit in a row. In how many different orders can they sit if no two

students from Bewton sit next to each other.

By both generating and directly computing obtain the number of the following:

b. All permutations of ("A","B","C").

c. Permutations of size 3 of (0,1,2,3,4,5).

d. Permutations of size 2 of (0,1,2,3,4,5,6).

e. Combinations of size 3 of (0,1,2,3,4,5).

f. Combinations of size 2 of (0,1,2,3,4,5).

g. Combinations of size 5 of (0,1,2,3,4,5)

Write down a python code to generate 3 sets of lottery tickets randomly from the pool of 300

tickets with an equal probability distribution, and keep in mind that if a set of the number already

selected in the first-month lottery, the same number is not allowed to repeat.

1. Create an application named Numbers whose main() method holds two integer variables. Assign

values to the variables. Pass both variables to methods named sum () and difference(). Create the

methods sum() and difference(); they compute the sum of and difference between the values of two

arguments, respectively. Each method should perform the appropriate computation and display the

results. Save the application as Numbers.cs

Write an application for a furniture company; the program determines the price of a table. Ask the user to choose 1 for pine, 2 for oak, or 3 for mahogany. The output is the name of the wood chosen as well as the price of the table. Pine tables cost R 100, oak tables cost R 225, and mahogany tables cost R 310. If the user enters an invalid wood code, set the price to 0 and allow the user to select an option up to 3 times . Save the file as Furniture.java.

Simply ATM

Requirements:

• The must be a main function that will display the menu and will ask for user's choice and pin.

The menu is shown below:

1 – Balance Inquiry

2 – Withdraw

3 – Deposit

X – Exit

• For each choice 1, 2 and 3, create an appropriate user-defined function for each task.
• Provide validation for input.

Score will be updated before encoded in BBL for the following:

• 40 points deduction if there is no user defined function created at all.
• 20 points deduction if all user defined function are void functions and no arguments.
