Solving probability word problems with not equally likely outcomes requires careful attention to the details provided in the problem. The key difference is that the probabilities of different outcomes are not the same, so you need to consider the probability of each individual outcome. Here are the steps to approach these problems:

Steps to Solve Probability Problems with Not Equally Likely Outcomes:

- Understand the Problem: Carefully read the problem and identify the events and their respective probabilities.
- List All Possible Outcomes: Identify all possible outcomes of the event.
- Determine the Probability of Each Outcome: If the probabilities are given, note them down. If not, calculate them based on the information provided.
- Calculate the Probability of the Desired Event: Sum the probabilities of the individual outcomes that satisfy the condition of the desired event.
- Simplify: If possible, simplify the final probability.
