Probability
Calculate probabilities and statistical distributions reliably.
Probability functions are fundamental for analyzing random events and statistical data. Calcul.io offers a variety of probability functions including distributions (normal, binomial, Poisson, etc.), cumulative distribution functions (CDFs), and probability density functions (PDFs). These functions are crucial for fields such as finance, insurance, and scientific research.
Our probability functions enable you to model uncertainties, calculate risks, and make informed decisions based on statistical evidence. Whether you are conducting experiments, performing data analysis, or simulating stochastic processes, Calcul.io provides the reliable tools you need for accurate probability computations.

Using Probability functions
Open any function in this category to review its accepted syntax, try editable inputs, and follow links to related operations. Function names are case-sensitive where shown. Start with the smallest working expression, confirm its result, and then combine it with variables or earlier calculator lines for a longer calculation.
The result stays beside the expression, so you can revise one argument at a time and compare the outcome without rebuilding the rest of your work. Use separate lines when you want to preserve intermediate values for checking or reuse.
