Question

In his class, Dale conducted a survey to observe the distribution of eye color. The results are summarized as follows:

Eye Color // number of students
blue // 20
Brown // 12
green // 10
amber // 8
hazel // 6
gray // 4

Answer 1

correct next question

If a student is randomly chosen from this group, what is the chance of selecting a student with blue eyes? Write your answer in the simplest form of a fraction.

Answer 2

Based on the survey conducted by Dale in his class, the distribution of eye colors among the students is as follows:

- Blue: 20 students
- Brown: 12 students
- Green: 10 students
- Amber: 8 students
- Hazel: 6 students
- Gray: 4 students

This information shows that the most common eye color among the students in Dale's class is blue, followed by brown, green, amber, hazel, and gray.

Answer 3

To calculate the probability of selecting a student with blue eyes, we need to find the ratio of the number of students with blue eyes to the total number of students surveyed.

Number of students with blue eyes: 20
Total number of students surveyed: 20 + 12 + 10 + 8 + 6 + 4 = 60

Therefore, the probability of selecting a student with blue eyes can be calculated as follows:
Probability = Number of students with blue eyes / Total number of students surveyed
Probability = 20 / 60
Probability = 1/3

So, the chance of selecting a student with blue eyes is 1/3.
