1. Binomial Distribution and Hypothesis Testing: Probability of non-germinating seeds in a packet, cumulative germination probability across multiple packets, hypothesis setup and test using normal approximation.
2. Poisson Process and Test for Rate Increase: Fault distribution in rugs, probability calculations for a given rug size, profit threshold analysis based on fault presence, and hypothesis test comparing two rates.
4. Discrete Sampling Distribution: Range of values from a sample drawn from a non-uniform distribution, calculation of specific range probability, full distribution of the statistic.
5. Continuous and Uniform Distributions: Derivation of probability density from a cumulative function, mixed distribution comparison, winning probability computation in a multi-spin game with conditions.
6. Normal Approximation to Binomial: Use of continuity correction and cumulative probability to form and solve a quadratic equation in p, and selection of a valid solution based on justification.
