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.

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 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
