Probability

• What is the definition of probability?

  The probability of something happening means how reliable it is to happen.
• Probability's vary between 0 and 1.

  A probability of 0 means something definitely won't happen.

  A probability of 1 means something definitely will happen.

  The bigger the number between 0 and 1, the more likely it is to happen.
