Beta distribution, a Rare card
In probability theory and statistics, the beta distribution is a family of continuous probability distributions defined on the interval [0, 1] or in terms of two positive parameters, denoted by alpha and beta, that appear as exponents of the variable and its complement to 1, respectively, and control the shape of the…

The facts on the card
The card carries these facts from its Wikipedia article.
- The beta distribution has been applied to model the behavior of random variables limited to intervals of finite length in a wide variety of disciplines.
- The beta distribution is a suitable model for the random behavior of percentages and proportions.
- In Bayesian inference, the beta distribution is the conjugate prior probability distribution for the Bernoulli, binomial, negative binomial, and geometric distributions.
Why it is Rare
Rarity in WikiCards follows a year of Wikipedia page views: the most read articles become Epic and Legendary cards. The Beta distribution article was read about 340,000 times in a year. ATK comes from the length of the article and DEF from its quality, so this card hits with 97 and blocks with 86: each hit it takes is cut by 34 %.
How to get Beta 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.
