Answer :
Final answer:
The best estimate for the probability question given, despite its incomplete context, is 80 percent.
Explanation:
The question seems to be about finding an estimated probability relating to an experiment or some numerical data, but due to typographical errors or missing context, the question is unclear. However, based on the reference material, it appears that statement 65.a suggests that we are looking for the probability that a randomly chosen student does not live within five miles of the campus. The best estimate of this probability is given by option A, which is 80 percent.
