1. Simulating experiments
Section 5.3
Simulating experiments

2. What are the chances? Three ways to answer this question:
Actually carry out an experiment
Develop a probability model (Ch. 6)
Start with a model, and then use a procedure to simulate repetitions
We’ll use technology
1. Could be costly, impractical, or logistically difficult Uses rules of probability 3. Quicker than repeating the real experiment.

3. Simulation
The imitation of chance behavior based on a model that accurately reflects the experiment under consideration
Effective for finding likelihoods of complex results.

4. Running a Simulation State the problem/describe the experiment
State the assumptions
Assign digits to represent outcomes
Simulate many repetitions
State your conclusions

5. Using Technology to Simulate
randInt(
TI-84 and 83:
Press MATH, PRB, #5
TI-89
Press CATALOG F3

6. Using Technology to Simulate
The command randInt(0, 9, 5) generates 5 random digits between any two specified values.
The command randInt(1, 6, 7) could be used to simulate rolling a die 7 times.
