Of all sixth graders, 70% sent a text message yesterday. Ten trials of a simulation are conducted and the data are recorded below.
62072, 34570, 80983, 04292, 83150, 36330, 96268, 14077, 77985, 13511
The numbers 0 through 6 represent students who sent a text yesterday, and the numbers 7 through 9 represent students who did not send a text yesterday.
Based on the simulated data, what is the probability that 3 or more of a group of 5 students randomly selected will send a text today? Explain.
