Question

Please write the following 4 programs in Java. [Programs completed but with errors, could someone re-create it?]

Please make it as simple as possible. [I am a beginner]

1. How would you use random numbers to represent the drawing of a playing card? Write a loop to test your answer by generating 100 randomly drawn cards and verify that they are in the correct range by printing and looking them over.

2. How would you use random numbers to represent the roll of a six-sided die? Write a loop to test your answer by generating 25 random rolls and verify that they are in the correct range by printing and looking them over.

3. How would you use random numbers to represent the roll of two six-sided dice? Write a loop to test your answer by generating 50 random rolls and verify that they are in the correct range by printing and looking them over.

4. Write a loop to generate 100 random numbers between 0 and 1000, and then display output which would be similar to the following:

Your random number test produced the following results:

Average: 104

Sum: 10444

Min: 23

Max: 900

[Thank you]
