Question 1

What is a pseudo-random number?

Accepted Answer

Computers generate random numbers through algorithms, called pseudo-random numbers. Not truly random, but sufficient for most purposes.

Question 2

Uniform vs normal distribution?

Accepted Answer

In a uniform distribution every number is equally likely; in a normal distribution values near the middle are more likely, matching natural patterns.

Question 3

What does the 'unique' option do?

Accepted Answer

It guarantees no repeated numbers — useful for draws and sampling. Note the count cannot exceed the number of integers in range.

Question 4

How do I ensure fairness?

Accepted Answer

Fairness depends on the random source. For security-sensitive uses (like passwords), use a Web Crypto API based tool such as the password generator.
