It's on a scale of 1 to 0 that a probability event may or may not happen.
The probability that an event will occur plus the probability that it will not occur equals 1.
These events are complementary. Let P(A) = probability event will occur. Then the probability it will not occur is: 1 - P(A).
an impossible event has a probability of 0, it will never occur a certain event has a probability of 1, it will always occur
Probability is a measure of the expectation that an event will occur or a statement is true. Probabilities are given a value between 0 (will not occur) and 1 (will occur).[1] The higher the probability of an event, the more certain we are that the event will occur.
How likely it is for an event to occur.
the probability a certain event will occur :-)
Probability is the measure of how likely an event is. ... The probability of event A is the number of ways event A can occur divided by the total number of possible.
Probability is the mathematical chance that an event will occur.
No; if it is certain not to occur the probability is 0.
That is the probability of that event.
Yes, the probabilty scale is from one to zero so is the probability is 0 it will definitely not occur
If the event will definitely occur, then its probability is 1.Not asked, but answered for completeness sake - if the event will definitely not occur, then its probability is 0. All probabilities lie between 0 and 1, inclusive.
