Answer on Question #47092 – Math – Combinatorics | Number Theory
True or false. Give reason.
The total number of possible sequences for processing 5 jobs on 4 machines is .
Solution
False.
Suppose machines admit simultaneous processing different jobs. The total number of possible sequences for processing 5 jobs on 1 machine is 5! Thus the total number of possible sequences for processing 5 jobs on 4 machines is .
Suppose we can choose only one job out of 5 to process on one machine. The total number of possible sequences for processing 5 jobs on 1 machine is 5. Thus the total number of possible sequences for processing 5 jobs on 4 machines is .
