In a school, 10% of the students have green eyes. Find
the experimental probability that in a group of 4
students, at least one of them has green eyes.
The problem has been simulated by generating random
numbers. The digits 0-9 were used. Let the number "9"
represent the 10% of students with green eyes. A sample
of 20 random numbers is shown.
