A bank of machines in a manufacturing shop breaks down according to the following interarrival time distribution. The time it takes one repairperson to complete the repair of a machine is given in the service time distribution:

INTERARRIVAL TIME (HOURS)	P(X)	RN	SERVICE TIME (HOURS)	P(X)	RN
.5		0.30		0-29		.5		0.20		0-19
1.0		0.25		30-54		1.0		0.25		20-44
1.5		0.18		55-72		2.0		0.30		45-74
2.0		0.13		73-85		3.0		0.12		75-86
3.0		0.08		86-93		4.0		0.08		87-94
4.0		0.06		94-99		5.0		0.05		95-99
		1.00						1.00

Simulate the breakdown of five machines. Calculate the average machine downtime using two repairpersons and the following random number sequence. (Both repairpersons cannot work on the same machine.)(Round your answer to 1 decimal place.)

RN: 80, 16, 12, 18, 13, 83, 77, 19, 69, 81, 12, 55, 19, 0, 77
