Step 1 of 3

Chapter 19 Simulation  Used to find probability in complex situations  Always start with a good model  Repetition of which a event will eventually be closer to the probability. Steps in assimilation: 1. Give a model 2. Assign digits to rep the outcomes 3. Simulate repetitions ( Random digits table) Tree diagram- representation of presenting complicated probabilities Different branches: represent different stages IF asked for an intersection (and) you multiply: Ex: what is the probability of surviving AND the transplant is a success. IF asked for a union (or) you add: What is the probability of living OR dying Chapter
