Basketball players tend to shoot in streaks so that a player who has just made a basket is more likely to make a basket on her second throw than if she had just missed the basket.

Personal estimates of the probability of uncertain events are called __________; mathematically determined statements about the likelihood of events with known frequencies are called __________.

When taking a 5-alternative multiple choice test, you are as likely to get all of the questions correct just by guessing as you are to get all of the questions wrong just by guessing.

This means that his probability of success would increase slightly above 2%.
