We can get this from the definition of probability.
Probability = number of outcomes / total number of outcomes.
In this case where we have ropes then:
Probability = the number of ropes held by the two at the same time / the total ropes.
Given the probability is 1/101,
Then the total number of ropes is 101.
Probability = number of outcomes / total number of outcomes.
