To find the probability of an event relies on past history of record data.

The relative frequency method of calculating the probability of an event relies on past history of recorded data for that event rather than on the number of favorable simple events out of the total number of outcomes of the event. For example, the probability that Joe will get a strike on his next try, given that he has bowled a strike 15 out of 20 times at the same bowling alley, is 15 over 20, 75%. Apply this same kind of thinking to the problem below.

Flights on Time	Flights Late < ½ Hour	Flights Late > ½ Hour
856	95	3

Your friend is arriving on the next flight from Chicago to Philadelphia. What is the probability that his plane will be on time? Record your answer to the nearest tenth of a percent. Show your method.

P(plane on time) =
