## Question 154:

I can do the math in all of my Probability & Stats 101 questions, but I can't tell which formula to use for what question. How can I interpret the word problems in order to know when to use which formula? Are there rules of thumb or words which will help me sort through the concepts quickly to determine which concept I need to use to answer a question? Or, can you point me to a good place to go to look at lots of problems and answers? I'm worried about my final exam in my college course. Thanks in advance. O
