### Probability Probability is the measure of the likeliness that an event will occur. Probability is used to quantify an attitude of mind towards some proposition of whose truth we are not certain. The proposition of interest is usually of the form `Will a specific event occur?` The attitude of mind is of the form `How certain are we that the event will occur......

### Probability A number between 0 and 1 which represents how likely an event is to occur. Events with probability equal to 0 never occur. Events with probability equal to 1 always occur.In data analysis, probability is normally defined in terms of the relative frequency of occurrence of an event which can be repeated many times. For example, if you repeatedly sam...

### Probability Probability can be generally defined as a measure of how likely some event will occur. The event could be an explosion, a lottery win or perhaps cancer induction. Mathematically speaking, the value of probability varies between 0 and 1 where 0 means an event will never occur whilst 1 means the event will definitely occur. Probability of a hazard s....

### Probability Probability: The likelihood that something will happen. For example, a probability of less than .05 indicates that the probability of something occurring by chance alone is less than 5 in 100, or 5 percent. This level of probability is usually taken as the level of biologic significance, so a higher incidence may be considered meaningful. The abbre...
