Probability distribution: A function that shows the probabilities of the outcomes of an event or experiment. Consider rolling a dice example. There are 6 possible outcomes (1,2,3,4,5,6).Strategic Practice and Homework Problems. Actively solving practice problems is essential for learning probability. Strategic practice problems are organized by concept, to test and reinforce understanding of that concept. Homework problems usually do not say which concepts are involved, and often require combining several concepts.
