 Amsco Integrated Algebra I: Empirical Probability
This is a free lesson from our course in Amsco's Integrated Algebra
This lesson covers concepts of probability.The probability is defined as the ratio of the number of outcomes favourable to the event divided by the total number of outcomes. E.g. when we toss a coin, we don’t know whether the coin will land with the head side or the tail side facing upward. We can describe this situation saying that the probability of heads is 1/2 and the probability of tails is 1/2 and it can be symbolized as: P (heads) = 1/2 or P (H) = 1/2 v/s P (tails) =1/2 or P (T) = 1/2. In cases of complex situation it may require a large number of trials and observing the outcomes taking scientific approach, and the outcome is empirical probability i.e. the empirical probability is the most accurate scientific estimate, based on large number of trials of the cumulative ralative frequency of an event happening.For example: If a coin is tossed 200 times and records reveal 122 "heads" & 78 "tails", from this experiment the empirical probability of getting head is P(Head) = 122/200 i.e. 0.61 or 61%.

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
