Description

"Random Events" Probability Preliminary PPT Courseware

The original meaning is that weather conditions such as wind, rain, cloudy, and sunny are difficult to predict.

It is extended to mean that many things in the world are accidental, and people cannot determine in advance whether these things will happen.

In nature and real life, we will encounter various phenomena.

From the perspective of whether the results can be predicted, they can be divided into two major categories:

The result of a type of phenomenon is always certain, that is, under certain conditions, its result can be predicted. This type of phenomenon is called deterministic phenomenon;

The results of another type of phenomenon are unpredictable, that is, under certain conditions, the result cannot be determined in advance. This type of phenomenon is called random phenomenon.

Determine which of the following events are inevitable, which are impossible, and which are random.

1. On Earth, the sun rises in the east every day.

2. There is a horse running at a speed of 70 kilometers/second.

3. Tomorrow, I will buy a sports lottery and win a grand prize of 5 million.

4. Connect three line segments with lengths of 3cm, 4cm, and 7cm in sequence to form a triangle.

5. Toss a fair coin, heads up.

Ball touch test: There are 4 black balls and 2 white balls in the bag. The shape, size, texture, etc. of these balls are exactly the same. Under the condition that the ball cannot be seen, a ball is randomly picked out from the bag.

(1) Is this ball a white ball or a black ball?

(2) If both kinds of balls are likely to be drawn, is the probability of drawing a black ball as high as that of a white ball?
