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. [latex]\frac{1}{2}[/latex]. 9. [latex]\frac{5}{8}[/latex]. 11. [latex]\frac{1}{2}[/latex]. 13. [latex]\frac{3}{8}[/latex]. 15. [latex]\frac{1}{4}[/latex]. 17. [latex]\frac{3}{4}[/latex]. 19. [latex]\frac{3}{8}[/latex]. 21. [latex]\frac{1}{8}[/latex]. 23. [latex]\frac{15}{16}[/latex]. 25. [latex]\frac{5}{8}[/latex]. 27. [latex]\frac{1}{13}[/latex]. 29. [latex]\frac{1}{26}[/latex]. 31. [latex]\frac{12}{13}[/latex]. 33.| 1 | 2 | 3 | 4 | 5 | 6 | |
