Two urns containing white and red balls. In probability and statistics, an urn problem is an idealized mental exercise in which some objects of real interest (such as atoms, people, cars, etc.) are represented as colored balls in an urn or other container. One pretends to remove one or more balls from the urn; the goal is to determine the ...
In statistics, a Pólya urn model (also known as a Pólya urn scheme or simply as Pólya's urn), named after George Pólya, is a family of urn models that can be used to interpret many commonly used statistical models. The model represents objects of interest (such as atoms, people, cars, etc.) as colored balls in an urn.
There are two urns each containing 100 balls. It is known that urn A contains 50 red and 50 black, but urn B contains an unknown mix of red and black balls. The following bets are offered to a participant: Bet 1A: get $1 if red is drawn from urn A, $0 otherwise Bet 2A: get $1 if black is drawn from urn A, $0 otherwise
In probability theory, the Mabinogion sheep problem or Mabinogian urn is a problem in stochastic control introduced by David Williams (1991, 15.3), who named it after a herd of magic sheep in the Welsh collection of tales, the Mabinogion.

An Urn A has 1 black ball and 2 white balls and another Urn B has 1 black ball and 3 white balls. Suppose we pick an urn at random and then select a ball from that urn. Let event A {\displaystyle A} be choosing the first urn, i.e. P ( A ) = P ( A ¯ ) = 1 / 2 {\displaystyle \mathbb {P} (A)=\mathbb {P} ({\overline {A}})=1/2} , where A ...
