Here you will find my package of past term-test questions – with their full solutions – customized to cover ALL the main sections of the chapters on your upcoming term test.
Check out the crazy Chapter 6 question that students in a previous year were expected to solve - and see the answer too!
One of the most common presentations of Bayes' law on the exam comes in the form of the false-positive and false-negative results that occur with medical testing. Understanding this one question will prepare you for all of the different components that make up Chapter 6.
The formula presented in the textbook for Bayes' theorem is pretty nasty looking. My advice - forget about it! I'll show you an easier (and equally valid) method that will get you full marks on the exam.
To really master this chapter, you'll need to know which wording to look for in the questions. Understanding the difference between join and conditional probabilities is especially key. I'll show you how.
Solving probability problems when no table is given can be extremely challenging. I'll show you a very simple set of steps to get you through questions with even the most complex wording - and get the right answer as efficiently as possible.
In this video I come back to the same data as in the last question, but this time I've replaced the given frequencies with joint and marginal probabilities. This has a drastic affect on our approach to solving the exact same questions. You'll see though, that by following the wording to the proper formulas, we will come to the same answers that we originally calculated.
Here are the short answer questions from the most recent exam written in ADMS 2320. It contains two very typical test questions; The first is from Chapter 6 and deals with most of the difficult aspects of that chapter... no worries though - I'll show you my system for identifying the critical wording and solving even the most challenging probability questions in just a few minutes, and the second question is an easy (but long) Chapter 4 question which I'll show you how to solve quickly.
