Dice Pool Probability Calculator

A quick and rough probability calculator for a friend interested in ttrpg mechanics.

Calculates the probability of rolling n or more successes when rolling a pool of dice, where each individual dice succeeds if it rolls on or above a success threshold (e.g. 4 or above).

Use the buttons on the side to change the parameters, and hover over points on the graph to view precise probabilities (rounded to 4 decimal places).
