0 < p ≤ 1
p being strictly positive here.
Probabilities are always from 0 to 1 inclusive. However, if the outcome is possible, p ≠ 0.
Thus the previous answer and the next answer are not quite correct.

probability is defined by the number of successes divided by the total number of outcomes in the sample space. for example. if you have a fair die and you want to know the probability of rolling a 1 or 2 then you have two possible outcomes that are successes and you divided by six total possible outcomes for rolling the fair die to get a probability of rolling a 1 or 2 as 2/6 = 1/3.
The axioms of probability are:
1. Let S be a sample space the P(S) = 1
2. for any event A, 0 ⤠P(A) ⤠1
3. If A and B are mutually exclusive events, the P(A U B) = P(A) + P(B)
from this you also have the rule that for any event A and B
P(A U B) = P(A) + P(B) - P(A â© B)

As regards a chance that an outcome may occur modifiers could be generally construed as follows:
probable means likely to happen
possible means less likely to happen
Answer: less likely to happen

Probability values always range from zero to one.
0 <= p{event} <=1.

Anywhere between 0 and 1.
