Final answer:
The question about the total number of tickets sold during the fall dance lacks the necessary information in the provided context. The options (a) 72, (b) 54, (c) 90, and (d) 64 are not applicable without specific details about ticket sales during the fall dance.
Step-by-step explanation:
Unfortunately, the question about the total number of tickets sold during the fall dance is missing the necessary information to provide an answer. We need additional data, such as the number of students that attended the dance and how many tickets each student purchased, to calculate the total number of tickets sold.
Without this information, any answer given would be a guess and not based on mathematical calculations.In regard to the information given, it seems to pertain to a different problem involving probability.
For example, if we were given the probability of each of the 12 students deciding to attend the fall dance, we could calculate the expected number of students attending, as well as the probabilities of at most four students or more than two students attending.
