Until fairly recently, you could throw a handkerchief over the variety of normal distribution questions you might expect to see in an EdExcel S1 exam. It would be one or more of: given a mean and a standard deviation, work out the probability that the random variable is larger or smaller than a given observation (very common) given a probability (as well as $\mu$ and $\sigma$, work out the observation (fairly common) given two observations and two probabilities, work out the mean and standard
