In an attempt to determine whether a candidate in an upcoming election actually had 60% of the vote, as indicated in a recent poll, his campaign team ran a simulation. The team members chose 20 randomly selected digits from 0 to 9, with the numbers 0 through 5 representing a success and the numbers 6 through 9 representing not a success. They then ran several trials and observed the following results:

Part A: Based on the results in the table, what was the number of trials?

Part B: If you were to construct a dot plot of the 60% proportion simulation table, which proportion(s) would contain the least number of dots?

Part C: Discuss collaboratively: Use the table to determine accurately the probability of success for all of the trials. How accurate would you suggest the poll was? Explain.
