This film looks at random experiments with exactly two possible outcomes. Such random experiments are called Bernoulli processes, after the Swiss mathematician. Simple examples explain the basics of calculating such processes. Elements such as the Bernoulli chain, the "Galton board" and Pascal´s triangle are introduced.
For a sample to be truly representative for an extrapolation or a forecast, it must be randomly selected. The film uses examples from everyday life to show that random evaluation can always lead to errors. Accordingly, forecasts are never really safe predictions, but always only of high probability.
This film is all about the relationship between the circumference and the diameter of circles. Using the example of a bicycle speedometer, we first introduce the number pi and the formula for working out the circumference of a circle. We then show how we get to the formula for working out the surface area of circles.
It is relatively easy to solve mixed quadratic equations by applying the binomial formulas backwards. The film shows how to recognize that a quadratic addition is necessary by using the equivalent transformation, the conversion and the root extraction. The video describes the procedure step by step.
