A pollster wants to minimize the effect the order of the questions has on a person's response to a survey. How many different surveys are required to cover all possible arrangements if there are 5 questions on the survey?

Number of choices for the first question=5
Number of remaining choices for the second question = 4
....
Number of remaining choices for the last question = 1
Number of possible arrangements = 5*4*...*1
