(or chance is how likely an event is to happen-Prob. goes from 0 (impossible) to 1 (certain)-Prob. can be shown as fraction, decimal or percent

To find probability desried event occuring divide the # of ways desried event could happen by total # possible outcomesProbability of = # of ways desried result CAN happenevent occured total # of possible outcomes
