Why are probabilities number 0 to 1? Why can't the number be greater than 1? Why can't it be negative?
-----------
Probability of an event = [# of ways to succeed]/[# of possible outcomes]
Since # of ways to succeed varies between zero and # of possible outcomes.
The probability varies from 0/# of poss to # of possible/# of possible
or 0 to 1
--------------
You cannot have a negative number of successes so the answer is never negative.
