Probability mass function, an Uncommon card
In probability and statistics, a probability mass function, discrete probability density function, probability function, or frequency function is a function that gives the probability that a discrete random variable is exactly equal to some value.

Power 84 (ATK + DEF): stronger than 25 % of WikiCards cards.
Probability mass function quiz: 3 questions
Three questions on the Probability mass function card, the way WikiCards duels ask them. Pick an answer, the facts are just below.
Find the missing word
A ______ PDF must be integrated over an interval to yield a probability.
Answer
continuous. A continuous PDF must be integrated over an interval to yield a probability. From the Probability mass function article on Wikipedia.
Which of these cards hits hardest (highest ATK)?
Answer
Rod Ferrell. Rod Ferrell 60 · Probability mass function 55 · Antagonist 51 · Goatee 42 ATK in WikiCards.
Which of these Wikipedia articles is read the most in a year?
Answer
Antagonist. Antagonist 170,000 · Henri Nestlé 93,000 · Probability mass function 73,000 · Graveyard orbit 56,000 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.
- The PMF is often the primary means of defining a discrete probability distribution, and such functions exist for either scalar or multivariate random variables whose domain is discrete.
- A PMF differs from a continuous probability density function in that the latter is associated with continuous rather than discrete random variables.
- A continuous PDF must be integrated over an interval to yield a probability.
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 mass function article was read about 73,000 times in a year. ATK comes from the length of the article and DEF from its quality, so this card hits with 55 and blocks with 29: each hit it takes is cut by 12 %.
How to get Probability mass function
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.
