Question 1

Statistical information: 90% of lottery winners go bankrupt within 5 years. Maria won the lottery. What is the most reasonable inference?
This is probabilistic reasoning. The statistical evidence (90% of lottery winners go bankrupt within 5 years. Maria won the lottery.) doesn't guarantee certainty, but it provides strong support for: Maria will likely face financial difficulties

Remember: Probability inferences are about likelihood, not certainty.

Question 2

Statistical information: 85% of students who study hard pass exams. Lisa studies very hard. What is the most reasonable inference?
This is probabilistic reasoning. The statistical evidence (85% of students who study hard pass exams. Lisa studies very hard.) doesn't guarantee certainty, but it provides strong support for: Lisa will probably pass

Remember: Probability inferences are about likelihood, not certainty.

Question 3

Statistical information: Most car accidents occur within 5 miles of home. John had an accident 3 miles from home. What is the most reasonable inference?
This is probabilistic reasoning. The statistical evidence (Most car accidents occur within 5 miles of home. John had an accident 3 miles from home.) doesn't guarantee certainty, but it provides strong support for: This fits a common pattern

Remember: Probability inferences are about likelihood, not certainty.

Question 4

Statistical information: Most car accidents occur within 5 miles of home. John had an accident 3 miles from home. What is the most reasonable inference?
This is probabilistic reasoning. The statistical evidence (Most car accidents occur within 5 miles of home. John had an accident 3 miles from home.) doesn't guarantee certainty, but it provides strong support for: This fits a common pattern

Remember: Probability inferences are about likelihood, not certainty.

Question 5

Statistical information: 7 out of 10 doctors recommend this medication. Your doctor prescribed it. What is the most reasonable inference?
This is probabilistic reasoning. The statistical evidence (7 out of 10 doctors recommend this medication. Your doctor prescribed it.) doesn't guarantee certainty, but it provides strong support for: This medication is probably effective

Remember: Probability inferences are about likelihood, not certainty.

Question 6

Statistical information: 75% of rainy days are cloudy. Today is rainy. What is the most reasonable inference?
This is probabilistic reasoning. The statistical evidence (75% of rainy days are cloudy. Today is rainy.) doesn't guarantee certainty, but it provides strong support for: Today is probably cloudy

Remember: Probability inferences are about likelihood, not certainty.

Question 7

Statistical information: 7 out of 10 doctors recommend this medication. Your doctor prescribed it. What is the most reasonable inference?
This is probabilistic reasoning. The statistical evidence (7 out of 10 doctors recommend this medication. Your doctor prescribed it.) doesn't guarantee certainty, but it provides strong support for: This medication is probably effective

Remember: Probability inferences are about likelihood, not certainty.

Question 8

Statistical information: 90% of people who exercise regularly are healthy. Tom exercises regularly. What is the most reasonable inference?
This is probabilistic reasoning. The statistical evidence (90% of people who exercise regularly are healthy. Tom exercises regularly.) doesn't guarantee certainty, but it provides strong support for: Tom is likely healthy

Remember: Probability inferences are about likelihood, not certainty.

Question 9

Statistical information: 90% of people who exercise regularly are healthy. Tom exercises regularly. What is the most reasonable inference?
This is probabilistic reasoning. The statistical evidence (90% of people who exercise regularly are healthy. Tom exercises regularly.) doesn't guarantee certainty, but it provides strong support for: Tom is likely healthy
