A survey finds that 40% of students ride in a car to school. Eri would like to estimate the probability that if 3 students were randomly selected, only 1 rides in a car.
To simulate this probability, she lets the numbers 0, 1, 2, and 3 represent a student who rides in a car to school and then 4, 5, 6, 7, 8, and 9 represent a student who does not ride in a car to school. She then has a computer randomly select 3 numbers. She repeats this process for 20 trials.
The results of these trials are shown in the table.
468 380 120 220
553 945 935 607
473 490 074 981
692 518 408 954
943 389 594 569
Based on this simulation, what is the estimated probability that only 1 of 3 randomly selected students rides in a car to school?
