necessaryh 2021-03-05While you are away on vacation, you ask a neighbor to water your ailing plant. If the plant does not receive water, it will die with a probability of 0.85. With water it will die with probability 0.5. You are 90 % certain the neighbor will remember to water the plant. You come back from the vacation and the plant is dead. What is the probability that the plant died because neighbor forgot to water it?
