1. Binomial and Hypothesis Testing: Modeling survival rate with binomial distribution, using normal approximation, and conducting a hypothesis test to detect changes in proportion.

2. Continuous Distributions and Variance: Working with cumulative distribution functions, calculating probabilities and variance via algebraic integration, and analyzing samples.

3. Poisson and Normal Approximations: Probability and distribution of discrete events using Poisson model, applying normal approximations, and hypothesis testing on rate increases.

4. Probability Density Functions: Determining parameters and characteristics (mean, median) of continuous distributions using algebraic integration.

5. Geometric and Expectation Modeling: Constructing a right-angled triangle model from random cuts, calculating expectations and probabilities using derived quadratic relationships.
