3 Methods to answer questions involving chance behavior Observing many outcomes of chance behavior. Relative Frequency Probability Model – Theoretical probability Simulation

Simulations with the TI-84   [MATH] [PRB] #5 -----randInt(lower, upper, how many) Stores in L1

5 Step process of a simulation:   1. State the problem or describe the experiment 2. State the assumption 3. Assign digits to represent outcomes 4. Simulate many repetitions 5. State your conclusion
