Exponential distribution quiz: 3 questions
Three questions on the Exponential distribution card, the way WikiCards duels ask them. Pick an answer, the facts are just below.
Find the missing word
It is a ______ case of the gamma distribution.
Answer
particular. It is a particular case of the gamma distribution. From the Exponential distribution article on Wikipedia.
Which of these cards hits hardest (highest ATK)?
Answer
Soling European Championship results. Soling European Championship results 86 · Exponential distribution 76 · Peruonto 73 · Vaccine storage 70 ATK in WikiCards.
Which of these Wikipedia articles is read the most in a year?
Answer
Exponential distribution. Exponential distribution 390,000 · Vaccine storage 4,000 · Peruonto 3,000 · Soling European Championship results 230 Wikipedia reads over a year.
In a duel, each round asks a question like these about the opposing card, with 15 seconds to answer.
The facts on the card
The card carries these facts from its Wikipedia article.
- It is a particular case of the gamma distribution.
- It is the continuous analogue of the geometric distribution, and it has the key property of being memoryless.
- In addition to being used for the analysis of Poisson point processes it is found in various other contexts.
Why it is Rare
Rarity in WikiCards follows a year of Wikipedia page views: the most read articles become Epic and Legendary cards. The Exponential distribution article was read about 390,000 times in a year. ATK comes from the length of the article and DEF from its quality, so this card hits with 76 and blocks with 68: each hit it takes is cut by 27 %.
How to get Exponential distribution
Open packs. Each pack holds five cards drawn from real Wikipedia articles, the rarest last, and the fifth card is always Rare or better. The odds are shown in the game. A free pack arrives every hour and two can wait, and the Coins you win in duels buy more packs.
