This probability distribution shows a typical grade distribution for a geometry course with 35 students. Find the probability that a student earns a grade of B or C. PLEASE HELPPP

0.71

Step-by-step explanation:

You basically add both amount of students that earned a B or C

After doing that you should get 25 in total, therefore leaves you with 25/35

Divide and you basically get your answer

0.71

2. angles qrt and qst both measures 156 degrees.

step-by-step explanation:  

we have been given a diagram of a circle and we are told that measure of arc qvt is 156 degrees.  

we can see from our given diagram that angle qrt and angle qst subtends to arc qvt.

since we know that angles subtended by the same arc at the circumference are always equal.

by angle subtended by same arc theorem, measure of angle qrt and angle qst will be equal to the measure of arc qvt.

therefore, angles qrt and qst both measures 156 degrees and 2nd statement is the correct choice.
