Its Bayes Theorem Calculator lets users enter prior probability, sensitivity, and false-positive rate to compute posterior probability. The interface is straightforward and focused on conditional probability use cases such as diagnostic testing. The tool is freely accessible with no mandatory subscription.
Two free random number generators that work in user-defined min and max range. Both random integers and decimal numbers can be generated with high precision.
This interactive GeoGebra activity demonstrates Bertrand's paradox using multiple random-chord generation methods. It lets users visually compare how different sampling assumptions produce different probabilities, making the paradox easy to explore for free in-browser.
The combination calculator provides a quick and easy way to determine the number of possible combinations for a set of items, given a specific subset size. Ideal for students, teachers, and anyone involved in statistics or probability, this tool simplifies complex calculations, saving time and reducing errors. By inputting the total number of items and the desired subset size, users receive an accurate count of all unique combinations, making it a valuable resource for educational purposes and practical applications alike.
This calculator can calculate the probability of two events, as well as that of a normal distribution. Also, learn more about different types of probabilities.
ToolDone offers a dedicated Bertrand's Box Paradox calculator that computes conditional probability for the classic box setup. It includes selectable scenarios and Monte Carlo simulation options to compare theoretical and empirical results. The tool is publicly accessible on the site with no mandatory paid plan.
