- Use the Empirical Rule to find the following probabilities. It is suggested that you draw a normal curve, label the x-values for 1, 2, and 3 standard deviations from the mean, and write in the probabilities between eachThe standard deviation of a discrete random variableo is the positive square root of its: O a. median. O b. mean. O c. variance. O d. mode. NE DUS PAGEVerify whether the given table represents a probability distribution. In those cases where a probability distribution is described, find the mean and standard deviation.
