Of all the seventh graders, 70% bought a school lunch yesterday. Ten trials of a simulation were conducted. The data are recorded below.
52461, 65709, 58324, 06381, 94381, 84947, 23046, 33789, 57802, 70633
The numbers 0 through 6 represent students who bought a school lunch yesterday and the numbers 7, 8, and 9 represent students who did not.
Based on the simulated data, what is the probability that 3 or more of the group of students randomly selected will buy the same school lunch the next time it is offered? Enter your answer in simplest form.
