The probability of picking the first number correctly is 1/56, since zero is included. Since the numbers are not replaced, the probability of the second is 1/55, the third, 1/54 and so on.
The probability of all events occurring is obtained by <I>multiplying</I> the individual probabilities.
The probability of either one event or another occurring is found by <I>adding</I> the probability of the individual events.
I hope this helps. Thanks for asking.
