Four roads lead away from the county jail. A prisoner has escaped from the jail and selects a road at random. If road I is selected, the probability of escaping is 1/8; if road II is selected, the probability of success is 16, if road II is selected, the probability of escaping is % and if road IV is selected, the probability of success is 9/10. D What is the probability that the prisoner will succeod in escaping? If the prisoner succeeds, what is the probability that the prisoner escaped by using road IV? By using road I?
