During the last hour, a telemarketer dialed 20 numbers and reached 4 busy signals, 3 answering machines, and 13 people. Use this information to determine the empirical probability that the next call will be answered in person.

it is 13/20, unless he dares call my number. Then it is zero.

To determine the empirical probability that the next call will be answered in person, you need to calculate the ratio of the number of people reached to the total number of calls made.

According to the given information, the telemarketer made 20 calls and reached a total of 4 busy signals, 3 answering machines, and 13 people. Therefore, the total number of people reached is 13.

To calculate the empirical probability, divide the number of people reached by the total number of calls made: 13/20.

So, the empirical probability that the next call will be answered in person is 13/20.

However, it's important to note that the empirical probability is based on the observed data, and it does not account for potential changes in circumstances, such as the specific number being called.
