Question 1192260: Roll a die 30 times. Construct a probability distribution and find the mean, the variance, and the standard deviation. Compare the results with the theoretical outcomes. Theoretical outcomes are the results using the formula for computing the population mean, μ=∑X/n, population variance, σ^2=(∑(X-μ)^2 )/n, and population standard deviation, σ=√((∑(X-μ)^2 )/n), where X=1,2,3,4,5,6 and n=6, since there are 6 faces of a die which are 1, 2, 3, 4, 5, and 6.
