Step 1: Firstly, determine the values of the random variable or event through a number of observations, and they are denoted by x 1, x 2, вЂ¦., x n or x i. The formula for a mean and standard deviation of a probability distribution can be derived by using the following steps: of red balls, in this case, is 0.67 with a standard deviation of 0.596. Standard Deviation (ЖЎ) = в€љ в€‘ (x iВ вЂ“В xМ„) 2 * P(x i) of red balls and their standard deviation. If two balls are drawn at random without replacement, then calculate the expected no. Let us take the example of a bag with 2 red balls and 4 blue balls. Probability Distribution Formula вЂ“ Example #2 of persons per family is 3.13 with a standard deviation of 0.808. Therefore, according to the survey, the expected no. Standard Deviation (ЖЎ) is calculated using the formula given below Mean (xМ„) is calculated using the formula given below Calculate the mean and standard deviation of the probability distribution. Let us take the example of a survey conducted in a certain to find out the expected number of persons in a family the following data is available.
