Probability is a numerical way to measure how likely an event is to happen. The term probability is defined as (the likelihood of an event happening or occurring). Most often it is referred to a (P/A) using this formula.
A probability of an event happening = Number of ways it can happen
Total number of outcomes
For elementary children, the probability is an area that children must understand that it refers to a chance, a guess, or a prediction. This concept can be confusing to young children because of the terms being used to represent probability. Probability can also be expressed by using vocabulary words such as "unlikely” or “likely," “equally” or “even chance”, "certain," or, “impossible”, "possible. “
The purpose of this downloadable poster is to supply the teacher with a visual poster to assist when teaching about data, basic probability, and chance. The first poster indicates the concept of least and most using targets. The 2nd poster shows the target from the impossible to the possibilities which include fractions and percentages.
