Video Summary
Five cars enter a roundabout from different directions, each leaving without repeating or returning to the entry point. There are 44 valid exit arrangements: 20 with a single transposition of two cars and 24 without any transpositions. The solution involves keeping track of car positions and ensuring no two cars share the same exit path or return to their entry position. Thus, adhering to these constraints leads to the conclusion that there are 44 possible combinations, with the answer being option B.
