Will it rain tomorrow? How likely is your favorite team to win the Super Bowl? Questions like these are answered through the mathematics of probability. Watch this artistic visualization of your odds of passing a test if you don’t know any of the ans...wers. (05:27)[more]

Calculating the Probability of Simple Events. In this video they show the basic idea and a few simple examples of calculating the probability of simple events! Uses a formula and putting numbers in the formula, explains how to solve the problems very... well. Video is good quality and good for all students as a review or initial learning of the topic.[more]

This is an introduction to probability. Probability is the chance of something happening. An example on probability is shown using the weather forecast for the week. The fraction answer is turned to a percent.

There is a lot going on in this video. For best viewing, the teacher or student should open to 'full screen'. The instructor is in the upper right-hand corner while discussing probability, while demonstrating in the middle. (04:13)

In the problem, there is a truth-teller and a liar. If you ask the right
question which is, "What would the other guy say is the correct door?" The person will always give you the incorrect door. Therefore, you will know which one is the correct do...or.This 6:49 long video shows how to use logic to solve this problem. A good warm-up activity.[more]

Existen dos tipos principales de problemas de probabilidad: los problemas de sucesos y los de probabilidad condicionada. La definición clásica de probabilidad nos dice que la probabilidad de que ocurra un suceso "a" es el cociente entre el número de ...casos favorables a ese suceso y el número de casos posibles. (6:00)[more]

Slide show shows how to use tree diagrams, compute the probability of outcomes when choices are equally likely, se the multiplication counting principle to find the total number of possible outcomes of a sequence of choices, find the greatest common ...factor and least common multiple of two numbers, solve ratio and rate number stories, and find the factors and prime factorizations of numbers
(Note: This is a slideshow of 32 slides. There is no sound.)[more]

This 1:20 long videos shows how to solve probability problems with marbles. The main formula is P=number of favorable outcomes divided by total number of outcomes. With that formula, you can solve probability problems with marbles. Uses animation.

In this clip from a math lesson on probability that teaches how to use a traditional calculator for probability distribution. Examples of shown of data to enter in the calculator and formulas and actual demonstration on the calculator. Video visual... quality is too dark.[more]
