2023年10月29日 · It is very important in probability to pay attention to the words “and” and “or” if they appear in a problem. The word “and” restricts the field of possible outcomes to only those outcomes that simultaneously satisfy more than one event. The word “or” broadens the field of possible outcomes to those that satisfy one or more events.

This section will take a look at probability involving the concepts of "AND" and "OR". It will be observed that there is a working relationship between set theory and probability.
