## Solutions to Odd-Numbered Exercises

1. probability; The probability of an event is restricted to values between [latex]0[/latex] and [latex]1[/latex], inclusive of [latex]0[/latex] and [latex]1[/latex]. 3. An experiment is an activity with an observable result. 5. The probability of the*union of two events*occurring is a number that describes the likelihood that at least one of the events from a probability model occurs. In both a union of sets [latex]A\text{ } \text{and }B[/latex] and a union of events [latex]A \text{and} B[/latex], the union includes either [latex]A \text{or} B[/latex] or both. The difference is that a union of sets results in another set, while the union of events is a probability, so it is always a numerical value between [latex]0[/latex] and [latex]1[/latex]. 7.
