Six tissues are extracted from an ivy plant infested by spider mites. The plant in infested in 19% of its area. Each tissue is chosen from a randomly selected area on the ivy plant. (a) What is the probability that there are exact four samples showing the signs of infestation and they are successive? Round your answer to four decimal places (e.g. 98.7654). P = i (b) What is the probability that there are exact three samples showing the signs of infestation and they are three out of four successive? Round your answer to three decimal places (e.g. 98.765). P = i
