To determine how many students in the class had brown eyes, you would need specific information that is not provided in the question. The number of students with brown eyes is not explicitly mentioned, so we cannot determine an exact answer based on the given information alone.
However, you could potentially find out the number of students with brown eyes by gathering data from surveys or observations within the class. You would ask each student what color their eyes are, and then count the number of students who report having brown eyes.
Without additional information or data, it is not possible to deduce the number of students with brown eyes in the class.
