Probability is the measurement of the likelihood of something happening

So, looking through the different questions, whether they have a graph or picture, you look at the numbers and divide by the total to determine the probablility.

This is a very broad question, probability is the possibility of something happening.  For example, if you were to roll a dice, each side would have a 1/6 probability of being landed on, since statistically, each one has an equal chance. Probability is written as a fraction.
