Formula for Variance and Standard Deviation of a Probability Distribution: Rolling a Die: Find the variance and standard deviation for rolling a die Selecting Numbered Balls: A box contains five balls. Two are numbered one is numbered and “3”, “4”, two are numbered The balls are mixed and one is selected at random. After a ball is selected, its “5”. number is recorded. Then it is replaced. If the experiment is repeated many times, find the variance and standard deviation of the numbers on the balls.
