Two dice are rolled. If a random variable X is defined as the absolute difference of the two numbers that appear on them, then the mean of X is

A pair of dice is thrown and the random variable X is defined as the sum of numbers that appear on the two dice. Find the mean or expectation of X.

Two dice are rolled. If a random variable X denotes the sum of the numbers on them and mu denotes the mean of X, then mu + P (X lt 5) + P ( X gt 9) + P ( x = 7) =
