In his class, Dan conducted a survey to observe the distribution of eye color.. the results are summarized as follows. Blue 20, brown 12, green 10, amber 8, hazel 6 and gray 4. If a student is randomly chosen from this group, what are the chances of selecting a student with blue eyes? Write your answer in simplest form of a fraction.
The total number of students surveyed is 20 + 12 + 10 + 8 + 6 + 4 = 60.
The probability of selecting a student with blue eyes is 20/60 which simplifies to 1/3.
Therefore, the chances of selecting a student with blue eyes is 1/3.
