<h3>What is probability?</h3>
Probability is the chance that an event will occur. The probabilty of an event is always fraction and lies somewhere between 0 and 1. A probability of zero means that an event can never occur while a probability of 1 implies that the event must surely occur.
The total number of drivers= 41 + 72 + 215 + 647 = 975
Number that wasn't intoxicated = 215 + 647 = 862
probability of not being intoxicated= 862/975 = 0.8841
