Which statistical method(s) will be appropriate to solve the below problems? Please provide proper reasoning.

Problem 6: Assume that IQ scores are normally distributed, with a mean u of 100 and standard deviation 0 of 15. What is the probability that a randomly selected person has an IQ sc0re: (i) More than 110'? (ii) Less than 125? (iii) Between 95 to 120? Example 7: Subway trains on a certain line run every half hour between mid-night and six in the morning- What is the probability that a man entering the station at a random time during this period will have to wait: (i) At least 20 minutes?
