Final answer:
The probability of an adult being single, given the survey data, is 14%, which is expressed as 0.14 in decimal form.
Step-by-step explanation:
The question posed is seeking the probability that an adult is single, given a set of data on marital status from a survey. According to the survey, 14% of adults are reported as single. Since the probability of an event is a measure of the likelihood that the event will occur, we can interpret this percentage as the probability of an adult being single.
In mathematical terms, the probability of an adult being single is simply 0.14 or 14%. This is found by taking the percentage of adults who are single (14%) and expressing it as a decimal, which is a common practice in probability calculations.
