Final answer:
To find the experimental probability of school cancellations in at least three of the next four years, one would count occurrences in the simulation where three or more years have a cancellation and divide by the total number of simulations, but the exact value cannot be determined without the actual data.
Step-by-step explanation:
The question asks about finding the experimental probability that weather will cause a school to be canceled in at least three of the next four school years. Without the table of simulated values provided, we cannot calculate the exact experimental probability. However, we can discuss how to approach this problem. If you were to have a table of simulated values, you would need to count how many sets of four years (represented by digits 1 through 4) have at least three years with a cancellation. Let's say this was represented as 1-1-1-0, with 1 indicating a year with cancellation and 0 indicating no cancellation. If you had 10 such sets and 3 sets had at least three '1's, the experimental probability would be calculated as (number of desired outcomes) / (total number of outcomes), which in this case would be 3/10 or 30%.
