In a given sample student size of 90, 2 persons are underweight, 61 healthy weight, 25 overweight and 2 obese. If we select a randomly a student from the university where the sample was drawn, what is the probability that the student would be:

a) Underweight

b) Healthy Weight

c) Overweight

Also, how can I show the p-value as the area under normal curve for each of the weight categories?
