What is the probability of rolling a two-digit number in a single roll of a die?

Jennette scored very low on a measure of extraversion

contained on a personality inventory she took in her psychology class. What can we predict about her likeliness to attend Saturday's homecoming dance? A) This would indicate a preference for quiet, reserved settings, so she probably won't attend. Incorrect. While she might be less likely to attend than somebody who is more extraverted, the relationship between individual traits and specific behaviors is weak at best. B) We would not do very well predicting her attendance at the dance. C) Despite a low score on extraversion, if Jennette has nothing better to do, she will probably attend. D) If her other scores on the inventory are high, she will probably attend the dance.
