A computer undergoes down-time if a certain critical component fails. This component is known to fail at an average rate of once per four weeks. No significant down-time occurs if replacement components are on hand because repair can be made rapidly. There are three components on hand and ordered replacements are not due for six weeks. (a) What is the probability of significant down-time occurring before the ordered components arrive? (b) If the shipment is delayed two weeks what is the probability of signifi- cant down-time occurring before the shipment arrives?

Question
A computer undergoes down-time if a certain critical component fails. This
component is known to fail at an average rate of once per four weeks. No
significant down-time occurs if replacement components are on hand because
repair can be made rapidly. There are three components on hand and ordered
replacements are not due for six weeks.
(a) What is the probability of significant down-time occurring before the
ordered components arrive?
(b) If the shipment is delayed two weeks what is the probability of signifi-
cant down-time occurring before the shipment arrives?
