This power point presentation offers a brief overview on how to calculate the probability of an event. The method shown is taking the part out of the total and making a fraction out of it. The time depends on the pace of the viewer.

Probability is defined as good outcomes over total outcomes in this slide show. The concept is explained through examples of a spinner and a word problem. (01:34)

Students learn that probability can be found by conducting an
experiment. For example, given a number cube that has the numbers 1, 2, 3, 4, 5, and 6 on its faces, students are asked to toss the number cube 6 times and use the results to determine t...he probability of rolling a given number, such as 4. Note that the theoretical probability of rolling a 4 is 1/6 (1 favorable outcome) / (6 possible outcomes), but the experimental probability may be different from 1/6. For example, if a student tosses the number cube 6 times and fails to toss a 4, the experimental probability will be 0/6, or 0. Students learn that experimental probability approaches theoretical probability as the number of trials increases. For example, if a student tosses the number cube 100 times, the experimental probability of rolling a 4 will approach 1/6. (04:19)[more]

Students learn that a simulation is a method of solving a problem
by conducting an experiment that is similar to the situation in the
problem. For example, a simulation can be used to find the probability
that a baby will be a girl. Since there... are two possible sexes for the
baby, girl and boy, one simulation would be to flip a coin, where heads represents girl and tail represents boy. Note that there are many possible simulations for a given problem. (01:56)[more]

This is a podcast that looks at setting up a probability of Random numbers used to simulate an experiment. An excel sheet is used to record the example data of batting sequence and make the probability calculations. Learn how to use the random num...ber generator in excel. (04:01)[more]

A student works on a project for her FLVS M/J Math 2 class about probabilities. She is interviewed on how she is going to set up her experiment with coins and what she thinks the outcome will be. She demonstrates the coin experiment and reports dat...a collected. (05:09)[more]

A demonstration of an experiment of probability using dice. He discusses the likelihood of the sequence he would get by rolling the dice. Not a very good visual quality video. (01:33)

Personal criticism on project forums and in video content is not allowed and will be deleted immediately.
Any violations of this rule could result in expulsion from the project so please, no insults or other negative
personal remarks.

Very harshly-worded criticism of content will also be deleted promptly. Please use your vote to express your
harshest feelings. Repeated violations of this rule can result in expulsion. If you must criticize another
person's hard work, then be nice about it.
