Final answer:
To estimate the probability, we can use the percentage from the opinion poll.
Step-by-step explanation:
To estimate the probability that the next person surveyed will be in favor of the proposal, we can use the percentage of people from the opinion poll who are in favor. In this case, the opinion poll indicates that 60 percent of people surveyed are in favor of the proposal. Therefore, we can estimate that the probability that the next person surveyed will be in favor of the proposal is also around 60 percent.
