The Little Purple Probability Book

Fine-tune your numerical mindset with a quantitative review that serves as a tool for perceiving probability in a new way. Whether you're a high school student, college student, or a test-prep candidate, this book's wealth of explanations and insights makes it a perfect learning companion.



Enjoy the benefits of your own short course in basic probability:

*Be able to think conceptually by understanding how key problems "fit" within the main topics of probability, permutations, combinations, and enumerations.

*Master basic probability using a simple "flowchart" to identify the correct formulas.

*Understand when to "add" probabilities and when to "multiply" probabilities.

*Be able to distinguish between events that are independent versus not independent and events that are mutually exclusive versus not mutually exclusive.

*Grasp key differences between permutations and combinations and look for key words such as "arrangements" or "selections" to indicate the correct problem type.

*Solve tricky permutation problems that involve repeated letters or numbers.

*Approach probability problems with a newfound confidence and competency.



This book is focused on those thinking skills that are essential for mastering basic probability. Such thinking skills make it much more likely that a person will be able to understand the "how" and "why" of problem solving, approach the subject in a conceptual way, and grasp those key principles that act as themes to bind related problems. These skills combine the science of math with the art of numbers.
