Which of the following can be considered as an activity based method to teach the concept of probability in middle school ?

Correct option is C

Activity-based methods involve students in hands-on activities to learn concepts. Option (c) is an example of an activity-based method because it involves students actively participating in an experiment and collecting data. This helps students to develop a deeper understanding of the concept of probability.
Option (a), Drawing a picture of a dice on the blackboard and talk about the possible outcomes, is not an activity-based method because it only involves passive listening and does not allow students to actively participate in the learning process.
Option (b), Giving the definition of probability followed by solving textbook questions, is not an activity-based method because it only involves rote memorization and does not allow students to explore the concept in a hands-on way.
Option (d), Asking students to find out information about probability from the internet, is not an activity-based method because it does not involve students in any hands-on activities. While students may learn about probability by researching it online, this is not the same as actively participating in an experiment or simulation.
Therefore, the only activity-based method is option (c).
