SUMMARY
The discussion focuses on calculating the mean and standard deviation of exam marks, assuming a normal distribution among 450 candidates. Given that 25 students scored 60% or more (first class) and 90 students scored less than 30% (failed), the mean and standard deviation can be derived using statistical methods. The normal distribution properties and the percentages of students in each category are crucial for these calculations.
