Welcome
Would you like to learn mathematics more easily and better prepare for quizzes and exams? We offer various tasks and tests that will help you improve your math skills. Try them out and see how your understanding and self-confidence grow!
Why here?
When using katestai.lt, the tasks and answer options of your tests are dynamically generated, so there is no possibility to memorize and reuse the correct answer from a previous task session.
This means that each test is unique and requires calculation and problem-solving each time anew.
Dynamic tests train mathematical calculation reflexes by repeating the same tests with different numbers and figures, teaching you to solve tasks without making foolish mistakes.

Combinatorics and probabilities
Grade: 5
Combinatorics is the branch of mathematics concerned with the counting, arrangement, and organization of objects or elements into sets, especially when the exact details of each object are less important than the overall assessment of the structure or pattern.
Probabilities, on the other hand, relate to the likelihood or chance of events. It is a branch of mathematics that deals with the amount of uncertainty or probability. It involves calculations that estimate the probability of different outcomes under certain assumptions or conditions.
