0.1 Assessment and grade distribution
The course grade is calculated using the following assessment weights.
| Assessment | Weight | Details |
|---|---|---|
| Quizzes | 20% | Four quizzes; only the best three are counted. No makeup quizzes. |
| Comprehensive homework | 15% | Four assignments |
| Collaborative flipped-classroom activity | 3% | Selected topic |
| In-class activities | 2% | Ongoing |
| Midterm examination | 25% | Scheduled around Week 7 |
| Final examination | 35% | Comprehensive |
| Total | 100% |
Final letter grades follow this scale.
| Letter grade | Percentage | Grade points |
|---|---|---|
| A | 90–100 | 4.00 |
| B+ | 85–<90 | 3.50 |
| B | 80–<85 | 3.00 |
| C+ | 75–<80 | 2.50 |
| C | 70–<75 | 2.00 |
| D+ | 65–<70 | 1.50 |
| D | 60–<65 | 1.00 |
| F | Below 60 | 0.00 |
Important attendance warning. Students are expected to attend all classes and are responsible for monitoring and recording their attendance from the first day of class. The maximum permitted absence is 25% of all classes. This 25% limit includes medical absences, social absences, and all other absences. A student who exceeds the limit will receive a failing grade regardless of academic performance. A valid excuse does not increase the 25% allowance; when applicable, University regulations may permit withdrawal rather than continued enrollment.
0.2 Course description
This course introduces the main ideas of probability and random variables. Topics include random experiments, sample spaces, events, axioms and rules of probability, equally likely sample spaces, counting techniques, conditional probability, random variables, expected value, moment generating functions, standard discrete and continuous distributions, and joint, marginal, and conditional distributions for bivariate random variables.
0.3 Student learning outcomes
By the end of this course, students should be able to:
- Identify basic probability experiments and interpret them.
- Apply the basic axioms and rules of probability.
- Distinguish between discrete and continuous random variables.
- Describe the main characteristics of standard probability distributions.
- Work with joint, marginal, and conditional distributions and related summary measures.
0.4 Delivery and learning approach
The course is designed as an interactive set of notes. Each chapter contains short explanations, worked examples, quick checks, and practice tasks. Students are encouraged to read actively, run the R code, and pause at each checkpoint before opening the solution.
0.5 Learning resources
Main textbook: Miller and Miller, John E. Freund’s Mathematical Statistics with Application
Additional references: Hogg, McKean, and Craig, Introduction to Mathematical Statistics; Mood and Graybill, Introduction to the Theory of Statistics.
0.6 How to use this course
- Read one chapter at a time.
- Run the R code chunks and modify them.
- Try each “Check your understanding” section before opening the answer.
- Use the chapter summary and practice exercises for review.
0.7 Chapter roadmap
- Introduction to R
- Techniques of Integration
- Set Theory and Counting Principles
- Probability Concepts and Conditional Probability
- Random Variables and Probability Distributions
- Bivariate Random Variables
0.8 Course conventions
Throughout the book, \(\mathbb{P}(A)\) denotes the probability of event \(A\), \(\mathbb{E}(X)\) the expectation of a random variable, and \(\operatorname{Var}(X)\) its variance. Monetary examples use generic currency units unless a currency is stated explicitly.
Recommended workflow: read the explanation, attempt the checkpoint without looking at the answer, run the R chunk, and then change one input to test whether you understand the result.
0.9 Visual guide
The colored boxes have the same meaning throughout the course:
- yellow introduces a formal definition;
- green states a theorem, rule, or important mathematical result;
- blue interprets a formula or explains why it matters;
- gray contains a worked example;
- burgundy highlights a finance application;
- purple highlights an actuarial application.
