Billiard table a '12 ft by 6 ft' table (similar to a snooker table but with much smaller pockets), and Asian four ball which uses a pocketless 8 ft by 4 ft table. Games such as bagatelle often had more than six holes, including straight through the bed in the middle of the table, a feature still found in bar billiards and bumper pool. There are novelty billiard tables, often for pool, that come in various shapes including zig-zag, circular, and (especially for bumper pool) hexagonal. A circular table featured prominently in the 1972 film "Silent Running". For the home market, many
Standard normal table probability that a statistic is between 0 (the mean) and Z. Note that for z = 1, 2, 3, one obtains (after multiplying by 2 to account for the [-z,z] interval) the results f(z) = 0.6827, 0.9545, 0.9974, characteristic of the 68–95–99.7 rule. This table gives a probability that a statistic is less than Z (i.e. between negative infinity and Z). The values are calculated using the cumulative distribution function of a standard normal distribution with mean of zero and standard deviation of one, usually denoted with the capital Greek letter formula_4 (phi), is the integral formula_4(z) is related to
