This probability distribution shows the typical grade distribution for a Geometry course with 35 students. Find the probability that a student earns a grade of A, B, or C. Enter a decimal rounded to the nearest hundredth.

.86

Step-by-step explanation:

There are 5+10+15 = 30 students that earned and A, B or C

P( A, B or C) = number of students that earned and A ,B , C / total

                    =30/35

                    =.857142857

   Rounded to the nearest hundredth

                   =.86
