### Random Number Generation Methods

Different methods generate random numbers with various properties:

**Uniform Distribution:**
All numbers have equal probability of being generated.
Formula: Random number = min + (random value × (max - min))

**Range Specification:**
To generate numbers between min and max:
Random = min + rand() × (max - min)

**Seed-based Generation:**
Pseudo-random number generators use a seed value to produce deterministic sequences that appear random.

**Probability Distribution:**
Different distributions (normal, exponential, etc.) can be applied to random values for specific applications.

Practical Examples

Worked Calculation Example: Generating 5 Integer Samples in [1, 50]

Range: Min = 1, Max = 50
Formula: R = Floor( Min + Random() × (Max - Min + 1) )

Sample Output Sequence: [14, 38, 7, 42, 29]

Common Random Number Generator Mistakes to Avoid

• Confusing Pseudo-Random Generators (PRNG) with Cryptographic Randomness (TRNG): Relying on standard algorithmic PRNGs for cryptographic security or key generation instead of hardware entropy.
• Seed Reset and Deterministic State Fallacy: Re-seeding a pseudo-random generator with the same seed value, which reproduces identical number sequences deterministically.
• Inclusive vs Exclusive Range Misinterpretations: Assuming generated ranges include the maximum upper bound ($[min, max]$) when the algorithm uses exclusive upper bounds ($[min, max)$).
• Modulo Bias in Integer Sampling: Using rand() % N to bound random integers, which introduces non-uniform distribution when $N$ is not a divisor of the generator's max state.
• Duplicate Sampling Without Replacement: Expecting unique non-repeating numbers when sampling with replacement from a fixed range.
• Non-Uniform Floating-Point Distributions: Assuming scaling Math.random() to large ranges preserves uniform probability density without floating-point granularity distortion.
