A probability experiment is conducted in which the sample space of the experiment is \( \mathrm{S}=\{1,2,3,4,5,6,7,8,9,10,11,12\} \), event \( F=\{5,6,7,8,9,10\} \), and event \( \mathrm{G}=\{9,10,11,12\} \). Assume that each outcome is equally likely. List the outcomes in F or G . Find \( \mathrm{P}(\mathrm{F} \) or G\( ) \) by counting the number of outcomes in F or G . Determine \( \mathrm{P}(\mathrm{F} \) or G\( ) \) using the general addition rule. List the outcomes in \( F \) or G . Select the correct choice below and, if necessary, fill in the answer box to complete your choice. - A. F or \( \mathrm{G}=\{5,6,7,8,9,10,11,12\} \) (Use a comma to separate answers as needed.) B. F or \( \mathrm{G}=\{ \} \) Find \( P(F \) or \( G) \) by counting the number of outcomes in \( F \) or \( G \). \( P(F \) or \( G)=\square \) (Type an integer or a decimal rounded to three decimal places as needed.)

Beyond the Answer
To determine the outcomes in \( F \) or \( G \), we first list the elements of both sets: - \( F = \{5, 6, 7, 8, 9, 10\} \) - \( G = \{9, 10, 11, 12\} \) Now, combining these elements while avoiding duplications, we have: - \( F \) or \( G = \{5, 6, 7, 8, 9, 10, 11, 12\} \) So, A is the correct choice: - A. \( F \) or \( G = \{5, 6, 7, 8, 9, 10, 11, 12\} \) Next, we find the probability \( P(F \) or \( G) \) by counting the number of outcomes: The total number of outcomes in the sample space \( S \) is 12. The number of favorable outcomes in \( F \) or \( G \) is 8 (the elements: 5, 6, 7, 8, 9, 10, 11, 12). Now, we can calculate the probability: \[ P(F \text{ or } G) = \frac{\text{Number of favorable outcomes}}{\text{Total outcomes}} = \frac{8}{12} = \frac{2}{3} \approx 0.667 \] Therefore, \( P(F \text{ or } G) = 0.667 \).
