If we test 100 power supplies for one year (8,760 hrs) and during this time ten fail. The estimate of MTBF is the total number of device hours (876,000) divided by the number of failures, which is 87,600 hours / failure. The probability that a power supply will survive to its calculated MTBF is 36.8%, no matter what the MTBF number is: R(t) = e
