You ask a neighbor to water a sickly plant while you are on vacation.
Without water the plant will die with probability 0.75.
With water it will die with probability 0.5.
You are 88 % certain the neighbor will remember to water the plant.
a)When you are on vacation, find the probability that the plant will die.
b)You come back from the vacation and the plant is dead. What is the probability the neighbor forgot to water it?
