1. What is the Random Number Generator?

Definition: This generator produces random numbers within a user-specified range, with options to allow or disallow repeats, set the quantity (up to 10,000), and sort the output. Numbers are displayed comma-separated, using cryptographically secure algorithms for unbiased randomization, suitable for lotteries, raffles, or games.

Purpose: It is used for giveaways, sweepstakes, charity lotteries, simulating dice rolls or coin flips, determining game turn order, or any scenario requiring true randomness.

2. How Does the Generator Work?

The generator uses a cryptographically secure random number algorithm to select numbers uniformly from the range \([ \text{min}, \text{max} ]\), ensuring each number has an equal probability:

\( P(\text{number}) = \frac{1}{\text{max} - \text{min} + 1} \)

Steps:

Enter the minimum and maximum numbers for the range.
Specify the quantity of numbers to generate (1–10,000).
Choose whether to allow repeats (if no repeats, quantity ≤ range size).
Select sorting option (unsorted, ascending, descending).
Generate numbers using a secure random algorithm.
Display the numbers comma-separated and, for ≤100 numbers, a frequency distribution chart.

3. Importance of Random Number Generation

Random number generation is essential for:

Fairness: Ensures unbiased outcomes in lotteries, raffles, or game turn orders.
Simulations: Mimics real-world randomness, like dice rolls (1–6) or coin flips (1–2).
Decision-Making: Randomly selects participants or orders tasks, removing human bias.

4. Using the Generator

Example 1: Generate 6 unique numbers for a lottery (1–49):

Min: 1, Max: 49, Quantity: 6, No Repeats, Unsorted;
Output (example): 42, 17, 31, 8, 25, 36;
Chart: Shows frequency (each ~1), confirming randomness.

Example 2: Simulate a dice roll (1–6) 10 times with repeats:

Min: 1, Max: 6, Quantity: 10, Allow Repeats, Ascending;
Output (example): 1, 2, 3, 3, 4, 4, 5, 5, 6, 6;
Chart: Shows frequency of each number (e.g., 3 appears twice).

5. Frequently Asked Questions (FAQ)

Q: How random are the numbers?
A: The generator uses cryptographically secure `random_int`, ensuring unbiased, true randomness, unlike pseudo-random methods.

Q: Can I simulate a coin flip or dice roll?
A: Yes, set min=1, max=2 for a coin flip, or min=1, max=6 for a dice roll, with repeats allowed.

Q: Why limit to 10,000 numbers?
A: This balances performance and usability. For larger sets, consider generating multiple batches or using numerical IDs.
