"WebAssuming the scores must be integers, there are exactly two scores that lie between a 5 and an 8 (noninclusive), and those are a 6 or a 7. That makes 2 out of 10, or a 1 in 5 chance. If the score can be any real number between 1 and 10, then the possible score range is 3 (from 8 − 5 ), and this probability would thus be calculated as 3 in 10.
