Researchers at a university have developed a safe metnod for rapidly detecting anthraxx 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 20 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 20. a. Find the probability that 13 or fewer anthrax spores are detected in the powder specimen. b. Find the probability that between 3 and 10 anthrax spores are detected in the powder specimen. a. The probability that 13 or fewer anthrax spores are detected in the powder specimen is (Simplify your answer.)

Researchers at a university 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 20 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 20.

a. Find the probability that 13 or fewer anthrax spores are detected in the powder specimen.

b. Find the probability that between 3 and 10 anthrax spores are detected in the powder specimen.

a. The probability that 13 or fewer anthrax spores are detected in the powder specimen is [   ] (Simplify your answer.)
