Rules of snooker Rules of snooker Snooker is a cue sport that is played on a baize-covered table with pockets in each of the four corners and in the middle of each of the long side cushions. It is played using a cue and snooker balls: one white , 15 worth one point each (sometimes played with fewer red balls, commonly 6 or 10), and six balls of different : yellow (2 points), green (3), brown (4), blue (5), pink (6), black (7). A player (or team) wins a (individual game) of snooker by scoring more points than the opponent(s), using the cue
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
