Teacher: In this task you will be given an answer to a question. You need to generate a question. The answer given should be a correct answer for the generated question.
Teacher: Now, understand the problem? If you are still confused, see the following example:
This list contains the top 25 accounts with the most followers on the social photo-sharing platform Instagram. As of May 2018, the most followed user is Instagram's own account, with over 235 million followers. Selena Gomez is the most followed individual, with over 137 million followers. Ten accounts have exceeded 100 million followers on the site.
Solution: who has the maximum number of followers on instagram
Reason: The answer is talking about the Instagram accounts that have the most followers. The question asking about the maximum number of followers. So this is a good example.

Now, solve this instance: In probability theory and statistics, the Poisson distribution (French pronunciation (pwaˈsɔ̃); in English often rendered / ˈpwɑːsɒn /), named after French mathematician Siméon Denis Poisson, is a discrete probability distribution that expresses the probability of a given number of events occurring in a fixed interval of time or space if these events occur with a known constant rate and independently of the time since the last event. The Poisson distribution can also be used for the number of events in other specified intervals such as distance, area or volume.
Student:
what is the parameter of the poisson distribution
