Hi there and you are welcome to this online revision platform, gcequiz.com. Here, we help students by providing them with numerous quizzes that they can use to better prepare for their end of year exams. A level Probability quiz 2 is just one of the many A level Mathematics quizzes that has been made available for you and here we will have a brief look on what probability is all about.

As a branch of mathematics, Probability is concerned with the numerical description which deals with how likely an event is to occur. It is important to note that the probability of an event is a number which is always between 0 and 1 with 0 indicating that the event is totally impossible and a probability of 1 indicating that the event is certain.

This topic sounds promising, right? If you are willing to be good in mathematics, all you have to do is go through all the mathematics quizzes available here.
