Question

PLEASE HELP I will give 50 points! PLEASE ANSWER CORRECTLY

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. 7918 7910 2546 1390 6075 2386 0793 7359 3048 1230 2816 6147 5978 5621 9732 9436 3806 5971 6173 1430 Experimental Probability = [?]% =

Answer 1

Answer: 45%

Explanation:

Given:

• A sample of 20 random numbers.

• The number "9" represents the 10% of students having green eyes.

Find:

• The experimental probability that in a group of 4 students, at least one of them has green eyes.

The number of groups which contains 9 is 9 and the total number of groups are 20.

So,

P = 9 / 20 = 0.45 = 45%

Therefore, the experimental probability is 45%
