Transportation Stat Courtney Quarles

1. 1. Statistics of Transportation safety<br />by Courtney Quarles <br />
2. 2. What is Probability?<br />Two types of Probability:<br /> -Theoretical probability<br /> -Empirical probability<br />Theoretical Probability:<br />Applies to situations in which the sample space only contains equally likely outcomes, all of which are known.<br />Empirical Probability:<br />Applies to situations on which we observe the frequency of occurrence of an event.<br />
3. 3. Words to know<br />Experiment: Any occurrence for which the outcome is uncertain, denoted by E.<br />Sample space: The set of all possible outcomes of an experiment, denoted by S.<br />Computing Empirical Probability<br />The empirical probability of event E is<br />P(E) = Observed number of times E occurs<br /> Total number of observed occurrences<br />
4. 4. Probability of an Event Not Occurring <br />The Probability of an event not occurring<br />The probability that an event E will not occur is equal to 1 minus the probability that it will occur.<br />P(not) = 1 - P(E)<br />
5. 5. Or Probabilities with Mutually Exclusive Events<br />Mutually Exclusive events<br />If it is impossible for events A and B to occur simultaneously, the events are said to be mutually exclusive.<br />Or Probabilities with mutually Exclusive Events<br />If A and B are mutually exclusive events, then<br />P (A or B) = P(A) + P(B)<br />
6. 6. What is the probability of not dying on an airplane?<br />P (not) = 1 - P(E)<br />P (not dying in airplane) = 1- P (not dying in airplane)<br />P = 1 - (1/11,000,000)<br />P = 0.9999999091<br />
7. 7. What is the probability of not dying on a Motorcycle?<br />P (not) = 1 - P(E)<br />P (not dying in motorcycle) = 1 – P (not dying in motorcycle)<br />P = 1 – (1/1020)<br />P = 0.9990196078<br />
8. 8. What is the probability of not getting struck by a metro bus?<br />P(not) = 1 - P(E)<br />P(not dying bicycling accident) = 1 - P(not dying in bicycle accident )<br />P = 1 – (1/4919)<br />P = 0.9997967066<br />
9. 9. What is the probability of dying on the subway metro bus?<br />P (not) = 1 - P(E)<br />P (not dying on the subway) = 1- P (not dying on the subway)<br />
10. 10. What is the probability of dying in a Motor vehicle?<br />P (not) = 1 - P(E)<br />P (not dying in motor vehicle accident) = 1- P (not dying in motor vehicle accident)<br />P = 1 - (1/84)<br />P = 0.9880952381<br />
