"Finding Probability Using Enumeration Method" Probability Preliminary PPT Courseware

Review review:

Generally, if in an experiment,

There are n possible outcomes, and they are all equally likely to occur.

Event A contains m outcomes,

Then the probability of event A happening is: P(A)=M/N

Steps to find probability:

(1) List all results (n) in a test;

(2) Find out the results (m) of the occurrence of event A;

(3) Use the formula to find the probability of event A: P(A)=M/N

think

"Throw two dice of the same texture at the same time" and

"Toss a die twice", does the result change?

"Throw two dice of the same texture simultaneously"

The points that appear on each of the two dice are 1 to 6.

"Throw a die twice"

The points that appear on each of the two dice are still 1 to 6.

induction

The relationship between "simultaneously" and "sequentially" random events:

"Two identical random events occur simultaneously" and

The result of "a random event happening twice" is the same.

summary

1. The meaning of “list method”

2. Use a tree diagram to list all results.

3. The relationship between "simultaneous" and "sequential" random events; the relationship between "replacement" and "no replacement".
