(a) Assuming that the time interval includes the left limit and all the times up to but not including the right limit, estimate the probability that an inventor has a best idea during each time interval: from 6 A.M. to 12 noon, from 12 noon to 6 P.M., from 6 P.M. to 12 midnight, from 12 midnight to 6 A.M. (Enter your answers to 3 decimal places.) 6AM-12PM 12PM-6PM 6PM-12AM 12AM-6AM (b) Do the probabilities add up to 1? Why should they? No, because they do not cover the entire sample space.Yes, because they cover the entire sample space. Yes, because they do not cover the entire sample space.No, because they cover the entire sample space. What is the sample space in this problem? 12AM-12PM6AM-6PM 6AM-12AMthe entire day
