NOTE:
It might be a good idea to experiment with flipping a coin before beginning
this lesson. Keep track of how many heads and tails you get and then have
the student imagine a two-sided disk which is different colors on each side.
(It would be even better if you actually have such a disk, but there's a good
chance that you won't so imagination will have to do.) Explain that you
can't get what you don't have and so if the target color is not on the coin,
it is impossible to flip that coin and get the target color. If the target
color is on the coin, then it is possible to flip and get the target color.
The use of "OR" might be confusing to the student. Work with the student
until the student can deal with "OR" statements.
