Cross out the part of the concept circle that does not belong. Then describe the relationship among the remaining parts. a coin landing on tails 8 out of 10 times. results based on an experiment. outcomes that should happen. rolling a sum of 9 twice in 5 trials.

Cross out: outcomes that should happen

Remaining parts: a coin landing on tails 8 out of 10 times, results based on an experiment, rolling a sum of 9 twice in 5 trials.

The remaining parts all involve probability or chance. The first involves the probability of a coin landing on tails, the second involves the results of an experiment which likely involved measuring or studying probability, and the third involves attempting to achieve a certain probability (rolling a sum of 9) through multiple attempts (5 trials).
