The Probability that a student will score more than 1700 points
Explanation:
The Mean Score is
Standard deviation is
The
The area
The required probability is given by the area between
This area represents
The Probability that a student will score more than 1700 points
It could be easily found like this-
The values are normally distributed. The Probability of the area under Normal Curve represents
Values greater than 1700 represents one-half of the area. The right wing of the normal curve represents values > 1700, hence probability
