Alex’s motorcycle didn’t start this morning. he was not sure if it was because of the battery or a damaged starter. if he replaces the battery, the engine will run with probability 0.7. if he replaces the starter, it will run with probability 0.2. he can try one of these in an hour. i was 85% certain that he would replace the battery. if the engine doesn’t run in an hour, what is the probability that alex replaced the battery (write it up to second decimal place)?
