What is certain, possible, impossible?
Three experiments and seven problems on the topic of “Probabilities of events."
• Rolling a die with different colors
• Tossing a coin
• Drawing a bead
Each experiment is conducted ten times, and the results are recorded in a table.
Afterwards, the students are to solve seven problems on probabilities (two of them are additional exercises for fast students). An answer sheet is used to check the students’ answers and should be discussed in class to formulate reasons for the results.
