Hurricane Harvey was said to be a 1,000 year storm.  Are we safe from this type of storm for the rest of our lives?

• Yes
• No

A statistician calculates the probability of an event in an experiment. After a dozen trials of the experiment, the statistician finds that the theoretical probability and the experimental probability differ. What is the likely reason for this?

• The statistician hasn't completed enough trials of the experiment.
• The statistician made an error in their calculations.
• The statistician made an error in constructing their experiment.
• The statistician has completed too many trials of the experiment.
