**Using standard deviation to find probability.? Yahoo Answers**

In probability and statistics, the standard deviation of a random variable is the average distance of a random variable from the mean value. It represents how the random variable is distributed near the mean â€¦... As the table shows, the value of 10 has a Z score of â€“1, which means it is one standard deviation below the mean. The value of 20 has a Z score of 0, which means it is equal to the mean. And the value of 30 has a Z score of 1, which means it is one standard deviation above the mean. Calculating Probability Within a Desired Range. The Z score allows you to calculate the probability that a
