Final answer:
Without the specific data on the total number of tickets and the number of adult tickets sold for "The Ransom" movie, we cannot determine the proportion of adult tickets sold among the provided choices.
Step-by-step explanation:
The question provided does not contain sufficient information to accurately determine the proportion of adult tickets sold for "The Ransom" movie. The options a. 0.4310, b. 0.5431, c. 0.5556, d. 0.7000 seem to be answer choices related to a different question, and there is no context connecting them with the movie ticket sales question. In order to calculate the proportion of adult tickets sold, one would typically need data such as the total number of tickets sold and the number of adult tickets sold, neither of which is provided here.
To answer such a question accurately, we require the specific details about the ticket sales for this movie. Without such information, it is impossible to select the correct option, and as such, I am unable to provide a definitive answer. If you have that data or can provide additional context, please do so that we may proceed with solving the problem accurately.
