Every year, many people hiking the Australian Outbacks are reported to be lost, and around 44% of them are eventually found by rescue missions. 73% of the people who were rescued were found to carry an emergency GPS locator, whereas 25% of the people who were not rescued were known to carry a similar locator. a. If a lost hiker is carrying an emergency GPS locator, what is the probability of them being rescued? Answer in exact fraction, or rounded to at least 4 decimal places b. If a hiker gets lost without a GPS locator, what is the probability that they will not get rescued? Answer in exact fraction, or rounded to at least 4 decimal places
