 Amsco Integrated Algebra I: Evaluating Simple Probabilities
This is a free lesson from our course in Amsco's Integrated Algebra
 
   
This lesson explains how to evaluate simple probabilities. In such a case two cases are possible:
• The Impossible Case:The probability of an impossible event is zero. For example, on a single roll of a die, what is the probability that the number 7 will appear?
P(E)= Number of ways to roll a 7/number of outcomes for the die =n(E)/n(s)=0/6=0.
• The Certain Case:The probability of an event that is certain to occur is 1. For example, On a single roll of a die, what is the probability that the number less than 7 will appear? (More text below video...)

(Continued from above)
P(E)= Number of ways to get number less than 7/number of outcomes for the die =n(E)/n(s)=6/6=1.
The probabilities fall between 0 and 1. It can be concluded that the probability of any event E must be equal to or greater than zero,and less than or equal to 1.i.e. 0 ≤ P(E) ≤1. The video below further explains with the help of several examples.

 
   

As many of you know, Winpossible's online courses use a unique teaching method where an instructor explains the concepts in any given area to you in his/her own voice and handwriting, just like you see your teacher explain things to you on a blackboard in your classroom. This particular lesson includes the teacher's instruction, practice questions as well as end-of-lesson quizzes for practice. As we mentioned above, you can enroll in our online course in Trigonometry by clicking here.

The format of Winpossible's online courses is also very suitable for teachers who are using an interactive whiteboard such as Smartboard on Promethean in their classrooms, because the course lessons can be easily displayed on such interactive whiteboards. Volume pricing is available for schools interested in our online courses. For more information, please contact us at educators@winpossible.com.
