they did not have a back-up copy machine. The first step in creating the simulation was to determine the time between repairs. The probability function for time between repairs is x = 6*square root (sqrt) of r‚ where r is the generated random number. First‚ a random number was generated. The next step to determine the time between repairs was to use the probability function of x=6*sqrt of r. The results of this calculation were placed in the second column of the excel worksheet. A third column was
