Six-red snooker Six-red snooker Six-red snooker (sometimes spelled six-reds, 6-red, and also known as super 6s), is a variant of snooker, but with only six initially on the table as opposed to the standard fifteen. In Six-red snooker, the traditional game of snooker is shortened, with fewer red-balls to pot. The game is played with all other rules unchanged, meaning that foul shots are more significant to the overall score. The maximum break in six-red snooker is 75, as compared to 147 for traditional snooker. The table is the same size as in the traditional 15-red game. The format was designed to
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
