Problem Statement
The question says Judy is conducting a survey about favorite ice cream flavors. She surveys 99 people at random and decides to ask one more.
We are asked to find out whether or not, her choosing to ask one more person and previously asking 99 random people are dependent or independent events.
Method
Before we begin our solution, we must first understand dependent and independent events and how to decipher which is which.
Two events are dependent when the occurrence of one event affects the probability of the occurrence of the other event.
To solve this question, we need to ask some questions and depending on the answers to the question, we will be able to determine what the answer is: dependent or independent.
The questions are:
1. Is it possible for the events to happen in any order?
- if yes, then move on to the second question below.
- if no, then the events are dependent.
2. Does one event in any way affect the outcome or odds
