Zero is considered a number. For example, 1 is obviously greater than zero. If you have one pencil and your friend has none, then you have more pencils than your friend, right? With this reasoning, five is greater than zero. The original question never said anything about the number zero not being permitted, so the equation becomes (3*5)+(0*2)=15. If the number of tails must be at least one, it has not been clearly stated in the question.
