Expert Solution

Given that,

One common system for computing a grade point average (GPA) assigns 4 points to an A, 3 points to a B, 2 points to a C, 1 point to a D, and 0 points to an F.

Now we want to find the GPA of a student who gets an A in a 3-credit course, a B in a 2-credit courses, a C in a 3-credit course, and a D in a 4-credit course.

Table For Calculation:-

Grade Point (Pi) No of Credit Courses (fi) Pifi
A 4 3 12
B 3 2 6
C 2 3 6
D 1 4 4
Total - Total=12 Total=28

[ Formula:-

]

So for this problem GPA is given by,

Now we put the value from table and we get,

​​​    [ Round to two decimal places ]  

Answer:- Correct answer is " 2nd Option. (2.33) "
