Imagine a situation where we want to store all possible outcomes of three consecutive coin flips *Heads, Heads, Tails*.
Imagine a situation where we want to store all possible outcomes of three consecutive coin flips using a decimal number, *Heads, Heads, Tails*.
Encoding this would happen as follows:
1. First we subdivide the range by the probability of each event happening. The probability of each is 50%, so that's simple. Referring above, we know that heads is represented by the top half of the range, and tails is represented by the bottom half of the range.
> Because the *first* coin flip resulted in *Heads*, the output value must be between $0.50$ and $1.00$.

The decoding process performs the same series of steps, but by asking a question instead of outputting a value.
1. Is the value between $0.00$ and $0.50$? If so, the first coin flip resulted in *Tails*. Otherwise if the value is between $0.50$ and $1.00$, the first coin flip resulted in *Heads*.
The above process can be repeated just like the encoding process until we've determined the output of the first three
