A fair 12-sided die numbered from 1 to 12 is rolled. Let \(X\) be the random variable representing the tens digit of the result obtained. Justify that \(X\) follows a Bernoulli distribution and specify its parameter \(p\).
Two fair dice are rolled: one four-sided die numbered from 1 to 4 and one eight-sided die numbered from 1 to 8. Let \(Y\) be the random variable representing the tens digit of the sum of the two numbers obtained. Specify the distribution of \(Y\).
