Articulate! Articulate! Articulate! is a board game from Drumond Park, for 4 to 20+ players aged 12 and up. Articulate! players describe words from different categories to their team as quickly as possible. The teams move round the board based on the number of words correctly guessed, and occasional spinner bonuses. Each round is 30 seconds long. Word topics include Object, Nature, Random, Person, Action and World. The object of the game is to get to the end before the other team. The game contains a circular board, 500 cards with 3,000 words, a spinner, timer, 4 playing pieces and instructions.
Random variable the set of all rational numbers). The most formal, axiomatic definition of a random variable involves measure theory. Continuous random variables are defined in terms of sets of numbers, along with functions that map such sets to probabilities. Because of various difficulties (e.g. the Banach–Tarski paradox) that arise if such sets are insufficiently constrained, it is necessary to introduce what is termed a sigma-algebra to constrain the possible sets over which probabilities can be defined. Normally, a particular such sigma-algebra is used, the Borel σ-algebra, which allows for probabilities to be defined over any sets that can be derived either
