In a school, 30% of the students have brown eyes. Find
the experimental probability that in a group of 4 students,
at least one of them has brown eyes.
The problem has been simulated by generating random
numbers. The digits 0-9 were used. Let numbers "2",
"4" and "8" represent the 30% of students with brown
eyes. A sample of 20 random numbers is shown.
Hint: First, count all of the random numbers that contain a 2, 4, or 8.
