Before the regional tournament, Tara and Emek prepared a fair warm-up schedule for their team. They created a spinner divided into 8 equal sections: 3 for passing drills, 2 for shooting practice, 2 for speed exercises, and 1 for stretching. They calculated the probability of each activity by comparing its sections with the total number of sections. The team learned that passing drills were most likely and stretching was least likely. Using the spinner results, Tara and Emek organized a balanced practice session that gave everyone a clear plan before the tournament.

Hint
Probability is the number of favorable sections divided by the total number of sections.
The warm-up spinner has 8 equal sections, and 3 sections are for passing drills. What is the probability of landing on passing drills?
3/85/81/38/3Correct! Passing drills have 3 sections out of 8 total sections, so the probability is 3/8.
Check that the numerator represents the activity sections and the denominator represents all sections.
Next🎉 Congrats! You got this question!
Hint
Use the probability of stretching and multiply it by the number of spins.
If the team spins the warm-up spinner 40 times, how many times would they expect to land on stretching?
Correct! Stretching has a probability of 1/8, and 40*(1/8) = 5.
Use the number of stretching sections compared with the total number of sections.

Hint
Compare the number of spinner sections for each activity.
Tara and Emek compare the probabilities of shooting practice and speed exercises. What can they conclude from the spinner?
Shooting practice is more likely because it comes before speed exercises.Speed exercises are more likely because they require more effort.Both activities have the same probability because they each have 2 sections.Stretching has the same probability as shooting practice because both are activities.Correct! Both shooting practice and speed exercises have 2 sections out of 8, so they have the same probability.
Probability depends on the number of sections, not the activity name or difficulty.
