You're an environmental engineer monitoring the leakage of contaminated material from a given landfill. Three monitoring wells, A, B, and Care used to verify if leakage has occurred. In 2020,50 leakages were reported, and you've parsed those out by the well that recorded the leakage and  the occurrence of rain at the same time. The following table contains your accounting of the 50 leakages. You randomly draw one of the leakages at random to study.  Rain occurring Rain not occurring Well A 5 17 Well B 4 10 Well C 3 11 a. What is the probability that the leakage was reported without rain?  b. What is the probability that the leakage was reported by well A or well B? c. What is the probability that the leakage occurred under rain conditions and reported by well C?  d. Given that the leakage occurred during no rain conditions, what is the probability that it was reported by well B?     May 05 2022 06:06 PM
