A basket contains 8 ripe (R) and 6 unripe (U) bananas. If three bananas are taken from the basket one after the other with replacement. Construct table that shows all the possible outcomes of the random experiment and all the values of the random variable R representing the number of ripe bananas.

3. Student Storage
by CodeChum Admin
Given the Student class that inherited from the Person class (the same ones from our lesson), construct another class called StudentAssistant. The class inherits from Student. What makes a StudentAssistant different from Student is that they have to render a fixed set number of hours. All student assistants are to render at least 40 hours of duty in a month. This maybe changed at any time by the Administrator.

2. Fraction/Mixed Fraction
by CodeChum Admin
Given the class Fraction in the code editor. Fill in the operations and display for the class Fraction. For plus and minus, think cross multiplication. times is straightforward, while divide has to do with reciprocals. toString should return the fraction in string format ("nume/deno" - as a String) but if denominator is 1, then the string should just contain the numerator.

2. Rectangle
by CodeChum Admin
A rectangle can be formed given two points, the top left point and the bottom right point. Assuming that the top left corner of the console is point (0,0), the bottom right corner of the console is point (MAX, MAX) and given two points (all "x" and "y" coordinates are positive), you should be able to draw the rectangle in the correct location, determine if it is a square or a rectangle, and compute for its area, perimeter and center point.

1. Air Conditioning Unit
by CodeChum Admin
Construct a class to represent an air conditioning (AC) unit containing the following attributes:
- brand - name of manufacturers like Samsung, LG, Carrier, etc.
- type - whether it is an inverter type or not
- power - represents the status of the AC unit whether it is turned on or not
- thermostat - levels go from 1 to 10
- temperature - levels go from 16 to 30 (in .5 intervals)
- It should have two constructors - one default and another that is overloaded
- default constructor
- sets all the numerical values to the least value as described above
- sets power to off, and type to inverter
- sets brand to "AC Brand"
- prints "Default Constructor"
- overloaded constructor
- accepts brand and type as arguments
- everything else is set to the same values as in the default constructor
- prints "Overloaded Constructor"

A lamella coupling according to the figure below has friction surfaces between the diameters 135 and 105 mm. The coupling works with the surface pressure 36 N / cm2 and the friction number between the friction surfaces is 0.3. The lamella package is compressed by springs with the spring constant 610 N / cm per spring.
- What force do the springs compress lamella packages with?
- How much are the springs compressed?
- Determine the transferable torque if we assume that the frictional force attacks the average radius
