A basketball player makes 160 out of 200 free throws. we would estimate the probability that the player makes his next free throw to be

The probability of the player making the next free throw will be based on the experimental probability that has already happened. So if he makes 160 out of 200, that is an 80% (4 out of 5) probability because this is equivalent to 80 out of 100 or 4 out of 5.
