Final answer:
To find the experimental probability, divide the number of people with hazel eyes by the total number of people who signed up. The experimental probability is 4/9.
Step-by-step explanation:
To find the experimental probability that the next person to sign up will have hazel eyes, we divide the number of people with hazel eyes by the total number of people who signed up. In this case, 8 out of 18 people have hazel eyes.
Experimental probability = Number of favorable outcomes / Total number of outcomes
Experimental probability = 8 / 18 = 4/9
So the experimental probability that the next person to sign up will have hazel eyes is 4/9.
