Using the given probability distribution, the next three random numbers(18, 89, 67) would correspond to arrivals of 10, 9, and 8 customers, respectively. Therefore, the total number of customers that would have arrived during this 30-minute time period is 10 + 9 + 8 = 27. However, since the distribution is only between 6 and 10 customers, we must cap the arrivals at 10 for each 10-minute interval. This means that the actual number of customers that would have arrived during this 30-minute time period is 10 + 10 + 7 = 27. Rounding down to the nearest whole number, the answer is 23.
