You decide to record the hair colors of people leaving a lecture at your school. What is the probability that the next person who leaves the lecture will have blonde hair
?
Express your answer as a simplified fraction or a decimal rounded to four decimal places.

Red 25
Brown 18
Black 40
Gray 42

⇒ 31 / 156 = 0.1987
Therefore, the probability that the next person who leaves the lecture will have blonde hair is 0.1987
