Let N be the set of natural numbers², and consider the random experiment of choosing a natural number randomly, so that all numbers are equally likely. Determine the sample space, the event space, and the probability function of this experiment. Then, write down a mathematical expression for identifying the event A which occurs when the selected number is divisible by 3, and calculate P (A). Do the three axioms of probability hold? If yes, prove your claim, and if no, employ a reasonable slight change to make the three axioms satisfied. Thinking about this statement might help: Since there are infinitely many natural numbers, the chance of any single number is zero. Thus, it holds for example that P (B) = 0, where B = {3,5, 6, 2020, 2021}.
