Supplementary Lesson
What to know
Begin this module by assessing what you have learned on the basic mathematical concepts and your skill in performing the diffrent mathematical operations which may help you understand the lessons in Ptobability.As you go through this module,thinkof the following essential questions: How is the number of occurances of an event determined?How does knowledge of finding the likelihood of an eventvhel you in your daily life?
The branch of mathematics that deals with uncertainty is pribability. Probability is a measure or estimation of how likely it is that an event will occur.Activities such as tossing or flipping a coino or picking a card from a standard deck of cards without looking each could be repeated over and over again and which have well-defined results are called experiments.The results are called outcomes.
Illustration:
When you roll a balanced die once,there are 6 possible outcimes which are 1,2,3,4,5 or 6.
Getting an even number includes 3 outcomeds;these are2, 4 and 6."Getting ab even number is called an event.
The set of all possible outcomes of an experiment is the sample space or probability space; and each individual outcome is a sample point.
