STAT 02360 · 3 cr · Advanced (300+)
Probability and Random Variables
Advanced credit and the rigorous layer above Stats I — Praxis probability loves this.
Suggested prep window: 3–4 weeks
Prerequisites to lock first
- Calc II helpful (integrals for continuous RVs)
- STAT 02260 Statistics I (you already have this)
A-grade strategy
- Always draw the sample space / tree / table before formulas.
- Separate discrete vs continuous recipes clearly in your notebook.
- Memorize common distributions (Bernoulli, Binomial, Poisson, Uniform, Normal, Exponential).

If you can do these cold, you are ready to start the Rowan section strong.
- Compute a conditional probability from a two-way table.
- Find E[X] and Var(X) for a simple discrete RV.
- Recognize when Binomial vs Poisson vs Normal is the right model.
