How to use this tool
- Choose a distribution and fill in its labelled parameters.
- Calculate the probability up to the threshold and any applicable point probability.
Things to know
- Normal probabilities use a numerical approximation. Binomial n is limited to 1,000 and assumes independent equal-probability trials.
- Normal distribution uses fixed arithmetic. Binomial trials: 0-1,000, successes within trials and probability 0-1; at most about 250,000 inner arithmetic steps.
- Use no more than 200,000 characters across the input and settings.
