About this calculator
Overview
Geometric PMF evaluates Geometric PMF for the math / probability-statistics library. Primary input cue: Trial [required] — field id `k`. Method anchor: P(X=k)=(1−p)^(k−1)p.
When to use
Use Geometric PMF when you already know the inputs and need geometric pmf without setting up a spreadsheet.
Inputs explained
- Trial [required] — field id `k`
- p [required] — field id `probability`
Formula / method
P(X=k)=(1−p)^(k−1)p (calculator id: geometric-pmf-calculator).
Worked example
Worked values: k = 4, probability = 0.25 → result = 0.10546875
Interpreting results
Read the primary output as geometric pmf under the method on this page.
Assumptions
- Inputs for `geometric-pmf-calculator` follow the on-page labels; values/shapes must match this operation.
- Units (when shown) must be consistent across inputs for geometric pmf.
- Real-number arithmetic is used unless geometric pmf explicitly needs integers.
Limitations
- Geometric PMF cannot invent missing inputs; incomplete forms stop short of a forged geometric pmf value.
- Display rounding can differ slightly from a CAS/symbolic exact form of geometric pmf.
- Complex/branch cuts and undefined points are not always interactively annotated for geometric pmf.
Important note
Educational mathematics tool. Check edge cases and domain restrictions when results look unexpected.
