Dandelions are studied for their effects on crop production and lawn growth. In one region, the mean number of dandelions per square meter was found to be 3. We are interested in the number of dandelions in this region.

(a) Find the probability of no dandelions in a randomly selected area of 1 square meter in this region. (Round your answer to four decimal places.)


(b) Find the probability of at least one dandelion in a randomly selected area of 1 square meter in this region. (Round your answer to four decimal places.)

Use the Poisson Distribution Formula to find the indicated probability. For a certain type of fabric, the average number of defects in each square foot of fabric is 1.8. Find the probability that a randomly selected square foot of the fabric will contain at least two defects. Round your answer to four decimal places. Hint: The answer is the complement of the probability that there is at most 1 defect
