Probability is the frequency that something in particular will happen, expressed in ratio with the frequency of anything happening. For instance, if you say that the probability of something is 0.25, then you can expect, over the long run, that repeated trials will result in 25% of the desired results and 75% of the non desired results.
A concrete example: In a standard deck of 52 cards, there are 12 face cards, the Jack, Queen, and King of Spades, Diamonds, Clubs, and Hearts. The probability of drawing a face card from a randomly shuffled deck is 12 in 52, or 3 in 13, or about 0.2308.
Probability is always a number between 0 and 1. A probability of 0 means that the desired event will never happen, and a probability of 1 means that the desired event will always happen. A consequence of this definition is that, if you say that the probability of something happening is p, then the probability of that something not happening is 1 - p.
