  2. Getting to Know You Diagram • In groups of three. • Get to know each other and find things you have in common. • Then fill in the Venn diagram of three overlapping circles on poster board. • In the areas that the circles connect, write the things that you have in common, and then individual facts about yourselves in your own circle. • Each team then presents your Venn diagram to the class.

  3. Me – Anne LevoHarrop • A little about me … • … teacher, mom, god-mom, daughter, sister, spouse … • … have studied a lot, still studying … • … math is still my first love • Email: levohaa@staff.ednet.ns.ca • Website: http://levohaa.hrsbteachers.ednet.ns.ca

  4. Getting to know you II • How many students have a job? • How many students LOVE cats? • How many students arrived here by bus today? • How many students have one (or more) tattoos? • How many students are in the room right now?

  5. Rights and Responsibilities • Alone: Brainstorm some "rights" you would like to have in this classroom. • Alone: Brainstorm some “responsibilities” as well. • With a partner share idea(s). • Talk over the ideas and brainstorm negative and/or positive consequences of each. • Large group: Come to consensus on rights and responsibilities. • Print on roll paper the rights and responsibilities students agree should be among their permanent classroom rights. • (Remember: The teacher retains the right to veto.)

  6. Pre-Assessment • Review Skills Survey

  7. Probability Outcomes • G2 demonstrate an understanding that determining probability requires the quantifying of outcomes • G1 develop and apply simulations to solve problems • G3 demonstrate an understanding of the Fundamental Counting Principle and apply it to calculate probabilities of dependent and independent events • G4 apply area diagrams and tree diagrams to interpret and determine probabilities of dependent and independent events • A6 develop an understanding of factorial notation and apply it to calculating permutations • G7 distinguish between situations that involve combinations and permutations • G8 develop and apply formulae to evaluate permutations and combinations • B8 determine probabilities using permutations and combinations

  8. Probability Vocabulary • Definition of Theoretical Probability • Probability is a likelihood that an event will happen. • We can find the theoretical probability of an event using the following ratio:

  9. Example • A bag contains 20 marbles. 15 of them are red and 5 of them are blue in color. Find the probability of picking a red marble. • Let’s first answer a few questions here: • If I am going to randomly pick a marble from the bag then what results can I have: • I’ll either pick a red marble or a blue one. • My next question is what the chances of picking a red marble are: • There are 15 red marbles and just 5 blue marbles. • It’s obvious that we have three times as many red marbles as blue marbles. • So, the chance of picking a red marble is more than that of the blue one.Therefore, the probability of picking a red marble is:
