Warm-up5.2 Probability Simulation 5.3 The Addition Rule and Disjoint Events Draw and fill in the table of the sample space of the sum of two dice. • Which sum has the highest probability? What is the probability? • Which sum is the least likely to occur? What is the probability?
5.3 The Addition Rule and Disjoint Events Notation: ________ ________ ________ Mutually Exclusive (disjoint)Non-Mutually Exlusive Ex. Selecting a person randomly Ex. E#33 pg 324 Suppose 80% can swim; 70% can from a room that is both male and whistle. Suppose 55% can do both. What is the % that pregnant. can either swim or whistle.

Common Test Mistakes On the gingko problem, the response variable was the change on their memory and learning tests. On the jalapeño plant problem, their were 72 plots and 6 treatments. If you mentioned that there were 4 locations and 3 plots for each treatment that was fine. It was block design. 3 parts of a well-designed expermiment Comparison – There must be a control group to compare Randomization - Units must be randomly assigned to treatment and control groups Replication – There must be multiple units in the treatment and control group Many of you were using sampling terms when describing an experiment.Do not do this if you want full credit on a free response.
Multiplication Principle When you have two independent events in the random experiment the multiplication principle gives you the number of possible outcomes. _______________________________________________ One of the formulas for independent events P(A and B) = P(A) * P(B)
