A bag contains 1 red ball, 3 blue balls, and 2 green balls. You pick 3 balls at random without replacement. Let R be the random variable counting the number of red balls chosen and G be the random variable counting the number of green balls chosen. b) Determine the joint probability mass function of the random variables R and G. Write it in a table with six entries. Also state how you can check your answer.
