I was trying to solve this question, but I was stuck when I red "INDEPENDENT NORMAL VARIATES". Can you please show me how to solve such question ?
The Mean and standard deviation of marks in English are 50 and 15 respectively. The corresponding values for Science module are 45 and 10 respectively. Assuming that the marks in the two subjects are independent normal variates. Find the probability that a student scores a total of marks lying between 100 and 120 in two subjects?
