Probability and Statistics can be difficult for students to master because the word problems require students to read and truly comprehend what is being asked before any solution can be attempted. Each probability lesson is taught by fully worked example problems that help students not only do well in class but truly understand the material taught. This series will provide the tools students need to succeed. What sets this program apart from other teaching tools is that the concepts are taught entirely through step-by-step example problems of increasing difficulty. It works by introducing each new concept in an easy to understand way and using example problems that are worked out step-by-step and line-by-line to completion. If a student has a problem with coursework or homework, simply find a similar problem fully worked on in the series and review for the steps needed to solve the problem. Students will be able to work problems with ease, improve their problem-solving skills and understand the underlying concepts of Probability and Statistics. This program covers the important topic conditional probability in Probability and Statistics. We begin by discussing what conditional probability is and why it is important. Next, we solve several problems that involve the essential ideas of conditional probability to give students practice with the material. The entire lesson is taught by working example problems beginning with the easier ones and gradually progressing to the harder problems. Emphasis is placed on giving students confidence in their skills by gradual repetition so that the skills learned in this section are committed to long-term memory.
