You are the expert. In this case I see naturals split into steps of
three and that, even though the set of natural numbers is infinite, any
natural number that you pick is finite and so it falls at the left end,
right end or the middle of one of these steps, with obviously equal
probability.

If it's obvious to you that these probabilities are equal,
then it must also be obvious to you what the probability is
that the number you pick is 42. So, what is that probability?

If you are serious the probability is zero because the sample space
here is infinite. If you wanna go the hitch-hikers' way the probability
of picking 42 is the same as the probability of picking the number that
results on computing 9x6. (You probably missed out "in this case
above".)
