Answer to Question #6787 in Statistics and Probability for Shashi
P(1) = P(2) = P(3) = P(4) = P(5) = P(6) = 1/6,
so the sequence
n1, n2, n3, ... , nN
of numbers of throws before 6 appearing should be uniformly distributed with expected value 1/6. We can use chi-square test to check the hypotesis that the dice isn't biased. The number of throws will depend on the chosen significance level and the dice - we need to throw a dice until the data will not convince us that the dice is biased.
