The probabilistic answer questions are the focus and hot issues of the college entrance examination in recent years. The common probability models and solving strategies for summarizing the probabilistic answer questions for college entrance examinations can help the students quickly identify the probabilistic solution to the probabilistic problem-solving model and select the problem-solving method in a targeted way. Solve the college entrance examination probabilistic answer questions. This article summarizes several commonly used probability models in college entrance examination probability answer questions, and points out their corresponding problem-solving strategies, for reference. Select a type 1 workshop A group has 10 workers, including 4 Female workers; Group B has five workers, including three female workers. Firstly stratified sampling was performed. Three workers were selected from the two groups for technical assessment.
