Accessories used for snooker include for the tip of the cue, of various sorts (needed often, due to the length of a full-size table), a triangle to the reds, and a scoreboard. One drawback of snooker on a full-size (12 ft × 6 ft) table is the size of the room (), which is the minimum required for comfortable cueing room on all sides. This limits the number of locations in which the game can easily be played. While pool tables are common to many pubs, snooker tends to be played either in private
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
