Nonstandard dice can produce interesting distributions of outcomes. You have two balanced, six-sided dice. One is a standard die, with faces having 1, 2, 3, 4, 5, and 6 spots. The other die has three faces with 0 spots and three faces with 6 spots. What are the possible values for the total number of spots Y on the up-faces when you roll these two dice? (Enter your answers as a comma-separated list.)
Each value will have the same probability. What is this probability? Enter answer as a fraction.
