Question

This probability distribution shows the typical grade distribution for a Geometry course with 35 students. Frequency 5 10 15 3 2 Find the probability that a student earns a grade of B

Answer 1

0.29

Explanation:

Total number of students = 35

Number of students who got B = 10

Probability that a student earns grade B :

Probability = required outcome / Total possible outcomes

P(grade B) = 10 / 35 = 0.2875

= 0.29
