Here's a math question for you!?

Question

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.

Answer 1

Favorable outcomes = 13 people answering
Total outcomes = 20 calls attempted

Probability is 13/20
13/20 = 65/100 = 65%

Answer 2

I am soo mathematically challenged but my guess would be a pretty good chance if the majority has actually answered the phone.
