Students learn that probability is the likelihood that a given event will happen, and probability can be found using the following ratio: (number of favorable outcomes) / (number of total outcomes). For example, the probability that the flip of a coi...n will come up heads is: (1 favorable outcome) / (2 possible outcomes), or 1/2. Note that probability can be written as a fraction (1/2), a decimal (0.5) or a percent (50%). Video is good quality and good for all students as a review or initial learning of the topic.(02:19)
