michael finds that35customers 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, , 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? enter your answer, as a fraction in simplified form, in the box.

Ответ:
Hence, the probability that, out of the next 5 customers, 4 or more will use a coupon is:
1/3
Step-by-step explanation: Total 15 trials were recorded as follows:
43454 24511 55555 43453 55315 25215 32235 43311 11154 13342 42514 13223 44215 45313 13324
Now, we are asked to find the probability that, out of the next 5 customers, 4 or more will use a coupon.
We know that probability is the ratio of number of favorable outcomes to the total number of outcomes.
Hence, number of favorable outcomes are: 5
(32235 43311 13342 13223 13324 )
Total number of outcomes are: 15
( Since 15 trials were performed)
Hence, Probability is: 5/15 = 1/3
Hence, the answer is: 1/3
