Drill 1/8/13The MD license plate for a car consists of 3 letters followed by 3 numbers. If you can’t use I, O, or U for letters, how many different possible plates can be created?
OBJECTIVEPerform probability simulations to model real-world situations involving uncertainty
PROBABILITY SIMULATIONS
Tool: something you can use to simulate your experimentRule: What outcome is assigned to what
SOME TOOLS
DiceCoinSpinnerRandom Number Generator (calculator)Others…
EXAMPLEThere are 6 cars to choose from. What tool would you use to simulate the probability of choosing each car? What rule would you use?
EXAMPLESuppose you are taking a True False quiz. What tool could be used to simulate the probability of each question? What rule would you use?
Rules for Tools
It is always safe to use a random number generator.Take the percent you are given and turn it into a fraction.The bottom number tells you how many section to have in your spinner or how many numbers to choose from.The top number tells you how many represent good outcomes.
DirectionsFor each following scenario design a simulation that can be used to determine the probability of the given outcome. Be sure to select a probability tool, decide on the rule, and describe the length and number of trials to determine the probability.
Example
At Hershey Park, accountants have found that 60% of the admissions are for children between the ages of 10 and 16. Design a simulation that could be used to determine the probability that 5 guests are between the ages of 10 and 16.
Example
There is a 50% chance that a baby that is born will be a girl. Design a simulation that could be used to determine the probability that a family with 4 kids has all boys.
Example
Suppose there is a 35% chance that a student will have a pet cat. Design a simulation that could be used to determine the probability that 3 randomly chosen students will have a pet cat.
PODMartin is planning a trip to Spain. They say that the rain in Spain falls mainly on the plain. Suppose there is a 70% chance that it will be sunny on any given day in Spain. Design a simulation that could be used to determine the probability that it will be sunny for all 7 days of Martin’s vacation.
