Probability theory quiz: 3 questions
Three questions on the Probability theory card, the way WikiCards duels ask them. Pick an answer, the facts are just below.
Find the missing word
Any specified subset of the ______ space is called an event.
Answer
sample. Any specified subset of the sample space is called an event. From the Probability theory article on Wikipedia.
Which of these cards hits hardest (highest ATK)?
Answer
Internal energy. Internal energy 71 · Probability theory 68 · Electric potential 65 · Adenine 59 ATK in WikiCards.
Which of these Wikipedia articles is read the most in a year?
Answer
Geographic coordinate system. Geographic coordinate system 380,000 · Human skeleton 170,000 · Probability theory 130,000 · Explosion 95,000 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.
- Although there are several different probability interpretations, probability theory treats the concept in a rigorous mathematical manner by expressing it through a set of axioms.
- Typically these axioms formalise probability in terms of a probability space, which assigns a measure taking values between 0 and 1, termed the probability measure, to a set of outcomes called the sample space.
- Any specified subset of the sample space is called an event.
Why it is Uncommon
Rarity in WikiCards follows a year of Wikipedia page views: the most read articles become Epic and Legendary cards. The Probability theory article was read about 130,000 times in a year. ATK comes from the length of the article and DEF from its quality, so this card hits with 68 and blocks with 44: each hit it takes is cut by 18 %.
How to get Probability theory
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.
