Hi, 1. The problem statement, all variables and given/known data A fair die is rolled n times. X denotes the number of times '1' is obtained. Y denotes the number of times '6' is obtained. I am first asked to state how X and Y are distributed (marginally) and to find their variance. 2. Relevant equations 3. The attempt at a solution Aren't X and Y distributed Binomially, with p = 1/6 and n? I.e. isn't the Variance of each then equal to: np(1-p) = 5n/36? Moreover, how may I determine their marginal distribution? I am not sure and would appreciate any feedback. Thanks!
