Distributions (Normal, Binomial, Poisson)

Summary

The normal distribution is the classic bell curve many metrics approximate, binomial models counts of successes across repeated yes/no trials, and Poisson models the count of events in a fixed interval.

• 1Sketch each distribution's shape and note where it typically shows up in real data.
• 2Learn the 68-95-99.7 rule for the normal distribution.
• 3Identify a real-world example (in a domain you know) that would fit each distribution.
