Researchers have developed a safe method for rapidly detecting anthrax spores in powders and on surfaces. The method has been found to work well even when there are very few anthrax spores in a powder specimen. Consider a powder specimen that has exactly 10 anthrax spores. Suppose that the number of anthrax spores in the sample detected by the new method follows an approximate uniform distribution between 0 and 10. a.) Find the probability that 8 or fewer anthrax spores are detected in the powder specimen.
