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.

Students learn that two events are dependent if the outcome of the first event affects the outcome of the second event. For example, taking a block out of a jar, then taking a second block out of a jar. And the probability of dependent events can be ...found by multiplying the probability of the first event times the probability of the second event. For example, if there are 4 blue blocks and 4 yellow blocks in a jar, the probability of taking a blue block out of the jar then a yellow block out of the jar is 4/8 times 4/7, or 16/56, which reduces to 2/7. The reason that the probability of taking a yellow block out of the jar is 4/7 rather than 4/8 is that a blue block has already been taken out, so there are only 7 blocks left in the jar. Video is good quality and good for all students as a review or initial learning of the topic.

In math, a simple way of thinking about probability is the chance of something happening against the chance of it not happening.
The expert in this video is Steve Jones uses a white board to demonstrate this concept.
