Answer:
Step-by-step explanation:
The number of ways 4 processes can be arranged is given by the number of permutations of 4 elements in 4 different positions (order of the process ), then
number of ways = number of permutations of 4 elements = 4! = 4 * 3 * 2 * 1 = 24
Since the first process that occupies the processing line can be in any of the 4 positions , but then the second one can be in any of the 3 remaining positions (since the first process had already occupied one position ) , the third can choose 2 ... and so on.
