The Range 100–200 in Numbers

N = 200 − 100 + 1 = 101
P = 1 ÷ 101 ≈ 0.99%
Whole numbers in the range 101
Chance of each number 1 / 101 ≈ 0.99%
Even / odd numbers 51 / 50
Chance of an even number 51 / 101 ≈ 50.50%
Draws for a particular number to reach a 50% chance 70

With repeats allowed, each draw misses a particular number with probability 1 − 1/101, so after k draws it has appeared at least once with probability 1 − (1 − 1/101)k. That first reaches 50% at k = 70.

Random Number Generator

This generator picks a random whole number between two bounds, both of them included. The number is drawn in your browser from its cryptographic random source, and every number in the range has the same chance. For example, it can help you find out random number between 100 and 200? Enter the lower bound (e.g. '100') and the upper bound (e.g. '200'), then press 'Generate'. On the result page you can draw several numbers at once, with or without repeats.

FAQ

Random number between 100 and 200?

It can be any of the 101 whole numbers from 100 to 200, each with about a 0.99% chance

How many numbers are there from 100 to 200?

101 whole numbers: 200 − 100 + 1 = 101, because both bounds are included. Even numbers among them: 51, odd: 50 — so an even result comes up with about a 50.50% chance.

How many draws does it take to get a particular number from 100 to 200?

With repeats allowed, a particular number has at least a 50% chance of appearing once it has been given 70 draws; after 69 draws the chance is still below 50%. Each draw is independent, so earlier misses do not make it «due».

How to pick several different numbers from 100 to 200?

Set how many numbers you need and tick «No repeats». The generator then draws without replacement, so you can get up to 101 different numbers — the whole range in random order.
