A fair six-sided dice has a "" on one face a '''' on two of its laces and a "" on the remaining three faces.
The dice is thrown twice, and is the random variable "the sum of scores from both throws''.
Find the probability that the total score is more than .

Important Questions on Valid Comparisons and Informed Decisions: Probability Distributions
A board game is played by moving a counter spaces forward at a time, where is determined by the following rule:
A fair six-sided dice is thrown once. half the number shown on the dice if that number is even; otherwise is twice the number shown on the dice. Write out a table showing the possible value of and their probabilities.

A board game is played by moving a counter spaces forward at a time, where is determined by the following rule: A fair six-sided dice is thrown once. half the number shown on the dice if that number is even; otherwise is twice the number shown on the dice. Find the probability that, in a single turn, a player moves their counter forward more than spaces.
