2. Using the tables in part 1, find the following probabilities: i. What is the probability that the student doesn't have the required GPA, he gets a scholarship and he missed the due date? ii. What is the probability that the student missed the due date? iii. Given that the student didn't miss the due date, what is the probability that he had the required GPA?

2. Using the tables in part 1, find the following probabilities:
i.
What is the probability that the student doesn't have the required GPA, he gets a
scholarship and he missed the due date?
ii.
What is the probability that the student missed the due date?
ii.
Given that the student didn't miss the due date, what is the probability that he had the
required GPA?

Given that the student didn't miss the due date, what is the probability that he had the required GPA?
TABLES FOUND IN PART 1:
P(GPA) = 0.401
P(Scholarship | GPA ) = 0.7756
P(Scholarship | No GPA) = 0.0651
P(On time | GPA and Scholarship) = 0.9646
P(On time | No GPA and No Scholarship) = 0.0179
P(On time | GPA and No Scholarship) = 0.0222
P(On time | No GPA and Scholarship) = 0.034
For Table 1, having GPA is a constant. So, the table of either scholarship or no scholarship, will be given by the ones, where the student has an accurate GPA.
So, P(Scholarship | GPA) = 0.7756 is the total probability of students, receiving the scholarship.
So, from here, TABLE 1:

For Table 2, not having GPA is a constant. So, the table of either scholarship or no scholarship, will be given by the ones, where the student does not have an accurate GPA.
So, P(Scholarship | No GPA) = 0.0651 is the total probability of students, receiving the scholarship.

Out of 1000,
No. of people with GPA = 401.
No of people without GPA = 599.
Based on this table we construct Table 3, a 1000 hypothetical two-way table.
