Consolidation: We focused on how the students solved the problem, noticing that it is easier to find all possible outcomes using a tree diagram. Today's problem (May 31): To activate our brains we looked at the probability of pulling out a red marble from this bag (2/4), and how the students knew that (there are 2 red marbles out of a total of ...

“What is the probability your friend actually has the disease (given a positive result)?” Construct a tree diagram: Use Bayes’ Theorem and your tree diagram to answer the question: There is a 66.2% probability that he actually has the disease. The probability is high, but …

Probability: A number from 0 to 1 (or 0% to 100%) that describes how likely an event is to occur. (p. 522) Theoretical Probability: The ratio of the number of equally likely outcomes in an event to the total number of possible outcomes. (p.540) Tree Diagram: A branching diagram that shows all possible combinations or outcomes of an event. (p. 522)

A tree diagram is a method of listing all of the possibilities where the end result resembles a tree. Example: List all of the possible outcomes when you flip a coin and roll a die. *this information can also be expressed in chart form. Examples: Find the probability of each using a tree diagram: You roll two standard dies. Find P(6, 6) Find P ...

Draw a tree diagram or create a table to show all the possible outcomes for this experiment. Find the theoretical probability of obtaining a sum of 5 on the two dice in this experiment. Show all your work. Describe how you could conduct this experiment by using two spinners instead of two six-sided dice.

Tree diagrams are used to display possible outcomes and count possible outcomes. Example: The school cafeteria sell sandwiches for which you can choose one item from each of the following categories: two bread (white or wheat), two meats (turkey or ham), and two condiments (ketchup or mustard). Create a tree diagram to show all possible choices.
