Question 1125663
for a one sample proportion, the SE for 0.995, or 99% confident, is
2.576*sqrt[p*(1-p)/n], and that equals 0.04
square both sides
6.636*0.5*0.5/n=0.0016, using 0.5 as the maximum sample size (most conservative).  Multiply both sides by n, then divide both by 0.0016
n=1036.875 or 1037 computers
