Calculate the probability that each of four people in an elevator will get off on a different floor, given that there are four floors in the building.

Hard Difficulty

Hard questions require advanced understanding and critical thinking. Here, your problem-solving skills are key, as these questions often involve complex scenarios needing in-depth analysis and well-structured responses.

Statistics question

Statistics questions assess your understanding of data analysis principles. Show your knowledge of probability, statistical inference, experimental design, and how you apply quantitative methods to interpret data and draw valid conclusions.

Here's a Hint

Think about this as an arrangement problem. First calculate the total possible ways people can get off (total sample space), then determine how many arrangements would result in each person getting off at a different floor.
