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 σ, the standard error is σ/√"n": Z tables are typically composed as follows: Example: To find 0.69, one would look down the rows to find 0.6 and then across the columns to 0.09 which would yield a probability of 0.25490 for a "cumulative from mean" table or 0.75490 from a "cumulative" table. Because the normal distribution curve is symmetrical, probabilities for only positive values of Z are typically given. The user has to use a complementary operation on the absolute value of Z, as in the example below. Z tables use at least three different conventions: This table gives a
