Michael finds that 35 customers at his grandfather's grocery store use a coupon. To simulate the behavior of the next 5 customers, he writes the numbers 1, 2, 3, 4, and 5 on cards and mixes them up. He writes down that 1, 2, and 3 represent someone using a coupon, and 4 and 5 represent someone not using a coupon.

Michael then randomly selects a card, puts it back, and records the number. He repeats this 5 times to represent 5 customers or 1 trial.

He repeats this experiment for a total of 15 trials. The results are shown in the table.
43454 24511 55555 43453 55315
25215 32235 43311 11154 13342
42514 13223 44215 45313 13324
Using this simulation, what is the probability that, out of the next 5 customers, 4 or more will use a coupon?
