What is probability, what can it values be, and what those values can mean (i.e. unusual, rare, likely, impossible, certain, uncertain). Also, what are the differences between empirical probability and theoretical probability. Next what is the addition rule and the multiplication rule. How can you tell the difference between them and when to use them? Also, what do the terms mutually exclusive/disjoint and independence and dependence events mean? How do they differ?
