What is the probability that a student has brown hair? (round to nearest hundredth)
To find the probability that a student has brown hair, we need to calculate the ratio of the number of students with brown hair to the total number of students.
The number of students with brown hair is 10 (boys) + 8 (girls) = 18.
The total number of students is 4 (black hair boys) + 5 (black hair girls) + 4 (blonde hair boys) + 6 (blonde hair girls) + 10 (brown hair boys) + 8 (brown hair girls) + 2 (red hair boys) + 1 (red hair girls) = 40.
Therefore, the probability that a student has brown hair is 18/40 = 0.45 (rounded to the nearest hundredth).
