You mentioned 'using a computer', so I am assuming that you mean by a program/script which randomly generates a name based on what you entered. In this case it can give the same output again.

According to the second part of your question, the program/script is run again on another computer. The probability that the same output is shown again depends on the number of students.

Example if there were 2 students, then the probability would be 1/2 or 50%

If there were 50 students the probability would be 1/50 or 2%
