what is in between 0 and 1 ? 1/2.
Technically, there are infinite answers, but the number that is in the middle of 0 and 1 is, $\frac12$
I hate to say this, but this question is quite unnecessary and takes up space (so that other peoples' questions may not get covered). Please refrain from posting these kinds of questions if you already know the answer.
In between? Infinite numbers are between 0 and 1.
There are infinite solutions, but if it was asking for a probability, you might want to use geometric probability.
