Knowing that data are normally distributed allows us to calculate the probability of obtaining a score greater than some specified value (option A) and also calculate what range of values are unlikely to occur by chance (option C). Therefore, both options A and C are correct and the answer is D. However, option B is not correct because the probability of obtaining a score of exactly 1 (or any other specific value) in a continuous normal distribution is zero.
