A student at a local college just completed 11 credit hours. His grade report is presented below. Course Credit Hours Grade
Calculus 4 B
Biology 3 C
Orientation 1 A
English 3 D
The university uses a four-point grading system, i. e., A = 4, B = 3, C = 2, D = 1, F = 0. What is the student's grade point average for this semester?
a. 2.27
b. 2.5
c. 2.75
d. 4.

Option c (2.27) is the right option.

Step-by-step explanation:

As per the question, the values are:

Credit hours                                       Grade                                 fiXi

       (fi)                                                   (Xi)                              

        4                                                  B = 3                                   12

        3                                                  C = 2                                   6

        1                                                   A = 4                                   4

        3                                                  D = 1                                    3      

Now,

hence,

The average will be:

=

On putting the values, we get

=

=                              

15% chance.

step-by-step explanation:

3/10 times, the 5 year old will get a tablet. 5/10 times, the 13 yer old will get a tablet. multiply both fractions to get 15/100 times, both would have a tablet.
