Test: Combinatorics and probabilities
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.
