The app provides topic-wise questions covering fundamental and advanced probability topics commonly studied in mathematics and statistics courses.

Students can practice conceptual questions, solve numerical problems, and monitor their performance using statistics. The app supports independent learning and systematic revision of probability concepts.

Topics Included
1. Basic Concepts of Probability

Random experiments, sample space, events, simple and compound events, and equally likely outcomes.

2. Types of Events

Mutually exclusive events, exhaustive events, complementary events, independent and dependent events, and equally probable events.

3. Classical Probability

Classical probability definition, probability value range, certain and impossible events, complement rule, and basic probability problems.

4. Addition Theorem of Probability

Addition rule, mutually exclusive events, general addition theorem, union and intersection of events, and related problems.

5. Conditional Probability

Definition of conditional probability, conditional probability formula, dependent and independent events, multiplication rule, and problem solving.

6. Bayes’ Theorem

Concept of Bayes’ theorem, prior and posterior probabilities, likelihood, total probability rule, and applications.

7. Random Variables

Definition of random variables, discrete and continuous random variables, probability distributions, probability mass functions, and probability density functions.

8. Mathematical Expectation

Expected value, properties of expectation, variance, standard deviation, and expectation-related problems.

9. Probability Distributions

Bernoulli trials, binomial distribution, mean and variance of binomial distribution, Poisson distribution, and distribution-based numerical problems.

10. Applications of Probability

Applications in games, statistics, risk analysis, reliability analysis, decision theory, and real-life situations.
