A researcher is planning to attend an international conference in his field. The conference organizer suggests 25 hotels for the attendees to choose from. Among them, 5 hotels are within 1 km, 10 hotels are around 3 km, 6 hotels are about 5 km, and the rest are more than 5 km, respectively, away from the conference center where the conference will be hosted. In terms of amenities provided by the hotels, the free WiFi availability is 40%, 60%, 80%, and 70%, respectively; and the chance of providing free continental breakfast is 20%, 40%, 50%, and 60%, respectively, depending on their distance away from the meeting place. After knowing the hotel room availability of 30%, 20%, 50%, 40%, respectively, based on their distance, what is the probability that this researcher can successfully book a hotel room within walking distance (≤1 km) to the meeting location if s/he wants to enjoy free WiFi and continental breakfast simultaneously
