Answer:
Step-by-step explanation:
To find the probability of selecting a student who scores 9, we need to determine the number of students who scored 9 and divide it by the total number of students.
Given the scores:
7, 6, 8, 9, 7, 8, 9, 10, 6, 4, 8, 6, 7, 5, 6, 10, 6, 8, 7, 7, 7, 5, 6, 8, 5, 7, 9, 6, 5, and 4
Count of students who scored 9: 3 (from the scores 9, 9, and 9)
Total number of students: 30
Probability of selecting a student who scores 9 = (Number of students who scored 9) / (Total number of students)
= 3 / 30
= 1 / 10
= 0.1
So, the probability of selecting a student who scores 9 is 0.1 or 10%.
