### What is a number 0 to1 that describes how likely an event is to occur?

A number between 0 and 1 represents a decimal probability of how
likely an event is to occur. It can be converted into a percentage
by multiplying it by 100. For instance 0.5x100 = 50% so 0.5 means
that something has a 50% chance of occurring. 0 means that the
event definitely won't occur, and 1 means that it definitely
will.

### Why can't probability be negative?

Because probability is a measure of how likely it is that some
event will occur. If there is no chance at all that the even will
occur than the probability is 0. If it will occur with 100%
certainty, then it is 1 or 100%
A negative number would have no meaning in terms of how likely
an even is to occur?
