Calculating Probability Using Ratios

This video tutorial teaches how to calculate the probability of an event using ratios. It begins with an introduction to probability and ratios, explaining how they represent fractions of a set or area. The tutorial highlights common mistakes in understanding probability, emphasizing the need for equal probability of events. It then demonstrates calculating probability with a spinner example, followed by solving a more complex problem involving fruits. By the end, viewers will understand how to calculate probability by creating ratios and avoiding common errors.
