Probability Theory includes worked examples. The SKILL.md runs to about 1,427 words, in the catalog's typical mid-range.
Probability Theory sits in the Science & Research category under the math-stats sub-topic in the ClaudSkills catalog. There are 10 related skills indexed alongside it; comparing a few before installing usually reveals which fits your workflow best.
These notes are auto-generated from features detected in the SKILL.md file and from this catalog's structure — they aren't part of the source repository.
Probability is the mathematical language of uncertainty. It provides the axiomatic foundation on which all of statistical inference rests: without probability, there is no hypothesis testing, no confidence intervals, no Bayesian updating, no regression. This skill covers the core machinery from sample spaces through the central limit theorem.
Probability Theory is a community-contributed Claude Code skill in the math-stats sub-category. It ships as a SKILL.md file that Claude Code auto-discovers under ~/.claude/skills/probability-theory/ and loads when your prompt matches the skill's trigger.
When to invoke it: Use when computing probabilities, reasoning about random events, working with probability distributions, or building the foundation for statistical inference.
The Probability Theory Claude Code skill is built for researchers, data scientists, academics, and analysts working with complex data and scientific literature. It's part of ClaudSkills (also referred to as Claude Skills or Claude Code Skills) — the open community-curated registry of 115,000+ SKILL.md files for Anthropic's Claude Code agent and the wider Claude ecosystem (Claude API, Claude Agent SDK).

SKILL.md from the source repository to ~/.claude/skills/probability-theory/SKILL.md and restart Claude Code. Both flows are detailed at claudskills.com/install/.SKILL.md file that lives under ~/.claude/skills/<name>/ and tells the Claude Code CLI agent how to perform a specific task (instructions, prompts, allowed tools). Skills are auto-discovered at session start. Probability Theory is one of 67,000+ skills indexed in the open ClaudSkills catalog, classified under the Science & Research category.
