Ya well, there is a slight problem here (in mathematical terms)

Suppose it is true that tossing

coins, each with 2 possible outcomes gives a total of

possible outcomes.

Now suppose I toss zero coins just once - don.t say this is not "physically possible", in mathematics this is irrelevant. So zero coins tossed just once has

possible outcomes. Can this be true?

Does it help to note that tossing

coins just once has exactly the same number of possible outcomes as tossing a

*single* coin

times? Well, tossing a single coin zero times reveals the starting face, that is only

outcomes.

What gives? Your homework is to provide a mathematical answer
