A shipping company claims that 95% of packages are delivered on time. A student wants to conduct a simulation to estimate the number of packages that would need to be randomly selected in order to find a package that was not delivered on time. What is an appropriate assignment of digits to carry out this simulation?

If 95% of packages arrive on time, then 5% are not delivered on time. Using two-digit numbers from 00 to 99 gives 100 equally likely outcomes, so 5 outcomes should represent a late package. Assigning 00–04 to “not delivered on time” represents 5 out of 100 outcomes, or 5%.
