"Finding Probability Using Enumeration Method" Probability Preliminary PPT Courseware 2

inevitable event;

An event that will inevitably occur under certain conditions,

Impossible event;

An event that is impossible to occur under certain conditions

Random events;

An event that may or may not occur under certain conditions,

Definition of probability

Generally speaking, if there are n possible outcomes in an experiment, and they are all equally likely to occur, and event A contains m of the outcomes, then the probability of event A occurring is P(A)=m/n

0≤P(A) ≤1.

The probability of a necessary event is 1, and the probability of an impossible event is 0.

Practice in class

1. There are 2 red balls and 2 green balls in a bag. Take out one ball at random, record the color and put it back. Take out another ball at will, record the color and put it back. Please estimate that you will get the red ball both times. The probability is ________.

2. A person has three shirts, red, white, and blue, and three pairs of red, white, and blue trousers. If the person randomly picks up a shirt and a pair of trousers, find the probability that they are exactly one set of white. ________.

3. Integers from 1 to 6 are written on 6 cards respectively. One card is randomly selected and replaced, and another card is randomly selected. Then, there is a probability that the number taken out for the first time can evenly divide the number taken out for the second time. how many?
