The new commands used in this program and others that may be useful. Select them below to learn more:
Initialises a new instance of the Random class. This allows you to generate random numbers.
If you specify the parameter y, this sets the seed to x to be used by the random number algorithm. The value of y can be omitted to use the current time as the seed number instead. Using the time of day as the seed gives the impression of truly random numbers.
Generates a random number between y (inclusive) and z (exclusive).
Investigate
Questions to think about with this program to check your understanding:
Identify two constants in the program that could be variables instead.
The numbers 1 and 7 could be constants in this version of the program although that would limit the program to only simulating the roll of a six-sided dice.
State what the two parameters are used for in the randint command in line 18.
The lowest and one above the highest number that can be generated by the random number algorithm.

Success Criteria
Change the program so that it:
- Asks the user what sided dice to roll in the main program.
- If an 8 or an 11 are rolled it outputs "You rolled an" followed by the result of the roll.
- If any other number is rolled it outputs "You rolled a" followed by the result of the roll.
Typical inputs and outputs from the program would be:
Roll a D6
You rolled a 3
Roll a D8
You rolled an 8
Roll a D10
You rolled a 4
Roll a D12
You rolled an 11
