As the table shows, there are 25 possible outcomes. Actually, you could know this without listing all possible values, because you have 5 outcomes for the first number, and the same 5 outcomes for the second number, leading to a total of
[tex]5\cdot 5=25[/tex]
possible couples.
So, the program will generate the couple (5,5) with a 1/25 chance, since (5,5) is one of 25 possible cases.
If you turn the number into decimal, you'll have
[tex]\dfrac{1}{25}=0.04[/tex]
