Question

there are 34 students in an english class. the students’ scores on the last exam are documented in the frequency table.
score frequency
a - range 6 students
b - range 8 students
c - range 4 students
d - range 11 students
f - range 5 students
if a c is considered the lowest passing grade, what is the probability that if you select a student at random, he or she will have passed the test?
give your answer as a percentage to one decimal place.
%

Explanation:

Step1: Identify passing grades

Passing grades are A, B, C, D (since C is lowest passing). So we sum their frequencies.
Frequency of A: 6, B: 8, C: 4, D: 11. Sum = \(6 + 8 + 4 + 11 = 29\)

Step2: Calculate probability

Total students = 34. Probability = \(\frac{29}{34}\)

Step3: Convert to percentage

\(\frac{29}{34} \times 100 \approx 85.3\) (rounded to one decimal)

Answer:

85.3%
