Probability based on a random experiment.
1. The telephone numbers for a region of a state have an area code of 570. The next seven digits represent the local telephone nukbers for that region. A local telephone number cannot begin with a 0 or 1. Your cousin lives within the given area code. What is the probability of not randomly generating your cousin's telephone number?
2. Decide if the events are mutually exclusive.
Event A: Randomly select a person who loves cats.
Event B: Randomly select a person who owns a dog.
