Answer:
66.89% probability (to the nearest hundredth) that a U.S. adult selected at random thinks the occupation of firefighter has very great prestige.
Step-by-step explanation:
A probability is the number of desired outcomes divided by the number of total outcomes.
Desired outcomes:
The number of adults who think that firefighters have very high prestige. So [tex]D = 689[/tex]
Total outcomes:
The total number of adults surveyed, so [tex]T = 1030[/tex]
Probability:
[tex]P = \frac{D}{T} = \frac{689}{1030} = 0.6689[/tex]
66.89% probability (to the nearest hundredth) that a U.S. adult selected at random thinks the occupation of firefighter has very great prestige.
