A player (or team) wins a (individual game) of snooker by scoring more points than the opponent(s), using the cue
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
