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?

What is the probability of drawing either a 3 or a heart from a regular bridge deck of cards?
The probability of A is denoted P(A) and the probability of B is denoted P(B). P(A or B) = P(A) + P(B) - P(A and B). Say P(A) = Probability of drawing a heart, which is 13/52. Say P(B) = Probability of drawing a three, which is 4/52. We now have to determine P(A and B) which is the probability of a heart and a three, which is 1/52. We now can determine the probability of drawing a heart or a three which is 13/52 + 4/52 - 1/52 = 16/52 = 4/13.
Is a negative divided by a negative a positive number?
negative times negative is positive negative divided by a negative is a postive negative times a positive is a negative negative divided by a positive is a negative
Is it possible to have a probability greater than 100?
It is not possible to have a probability greater than 1. All probabilities are between 0 and 1, inclusive.
What is the ratio of the number of ways an event can occur to the number of possible outcomes?
The term is probability (theoretical probability), or how likely a given event is to occur.
When a number cube is rolled once what is the probability of getting an odd number greater than five?
it depends on how many numbers are on the number cube. if it only goes to 6, then the probability is 1/6. if it goes to 8 then the probability is 2/8. and so on and so on...
Why cant a negative fraction represent a probability?
Probability is a ratio of two counts: both of which MUST be positive. Their ratio cannot be negative.
Can -0.51 be a probability?
No. The probability cannot be negative.
Can probability values be negative?
No. Probability values always have to be positive.
Does a negative z score yield a negative probability value?
no, z score can be negative but a probability is a always positive between 0 and 1.
Can probability be negative?
No, it can't.
When cant you have theoretical probability?
After an event
Can a probability of some event be negative?
no
Can the expected value of a discrete probability distribution be negative?
Yes it can be negative.
Can probability outcomes be expressed as negative integer's?
The outcomes of a trial can be a negative integer but the probability of any outcome must be in the range [0, 1].
What is the probability of winning at Blackjack?
You cant win
Can probabilty be negative?
Yes it can. E.g there may be a probability it may rain tomorrow. See, negative. Negative probability is like an opinion of your own except probabilities aren't opinions, anyway you get what I mean.
Can the experimental probability of an event be a negative number.if not why?
No; because probability can never be less than zero.
