Can anyone at least help me get this problem started? I can't figure it out...

The table below represents the probability distribution for service time in minutes. Number of breakdowns Probability 3 0.25 4 0.34 5 0.16 6 0.25 a) Suppose that two digit twodigit random number ranges are assigned to each of the possible service time, starting from Ell as the lower limit for 1 minute of service time and IIIEI as the upper limit for4 minutes of service time. Indicate the random number ranges in the following table for each possible value of service time. Senrice time Lower limit Upper limit 3 Suppose that for a trial the random number 92 was drawn . What would be the simulated service time
