Experimental probability that in a group of 4 students, at least one of them has hazel eyes is 85%.
The experimental probability of an event occurring is the number of times that it occurred when the experiment was conducted as a fraction of the total number of times the experiment was conducted.
According to the question
In a school, 30% of the students have hazel eyes.
The number of hazel eyes in data is 17
The total number of data sets are 20.
Experimental probability = × 100%
= 85%
Hence, experimental probability that in a group of 4 students, at least one of them has hazel eyes is 85%.

Answer:
90%
Step-by-step explanation:
Answer:2/5(x)= 34
Step-by-step explanation:2/5 of the total points are equal to his total score. His total score is 34, so 2/5 times total score would equal his score. Total points scored is 85.
2/5(x) =34
X=34/(2/5)
X=34/.4
X=85
