Determine how many possible values there are for the following discrete random variable \"sum of your next roll of two six-sided die.\" What is the likelihood that the sum of two six-sided die equals 9? Determine whether the following distribution represents a valid probability distribution. 0 Yes O No, not all the probabilities are positive. 0 No, X * P(X) = O. O No, not all the X values are positive. A coin is tossed three times. The following table summarizes the experiment. What is the following table called?
