In a school, 60% 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. 7918 7910 2546 1390 6075 1230 2386 0793 9436 3806 2816 6147 5978 5971 6173 7359 5621 9732 3048 1430 2122 13 20 =0.65 = [?]% = Experimental Probability
