Question

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

Answer 1

Given that in a group of 4 students at least one has green eyes.

Also, the number 9 represents the 10% of the students with green eyes.

From the 20 random experimental numbers given, the number 9 appeared in only nine of them.

The experimental probability in percentage will be:

`(9)/(20)\ast100\text{ = }45\text{ percent}`

ANSWER;

45%
