Bell Ringer Chapter 7 Review A skateboarding ramp is called a wedge. In order to keep the wedge from moving while being used, it must be filled with sand. Below is a sketch of the dimensions used for one to be built. A.) What square footage of material would be needed to build the wedge? B.) How much sand would you need to completely fill the wedge?

Chapter 8 Probability

What is probability? Probability is the chance that an event will happen… Probability = number of favorable outcomes number of possible outcomes EX: A box contains 5 green pens, 3 blue pens, 8 black pens, and 4 red pens. A pen is picked at random. A. What is the probability the pen is green –or- P(green)? B. What is the probability the pen is blue or red –or- P(blue or red)?

Example: A computer company manufactures 2,500 computers each day. An average of 100 of these computers are returned with defects. What is the probability that the computer purchased is not defective?

Homework: You have 5 minutes to copy the problems… From page 376, copy the given information along with the problems for #11-18.

Counting Outcomes 1. Tree Diagrams 2. Fundamental Counting Principle

How to Use a Tree Diagram: A hat comes in black, red, or white and medium or large. How many outcomes can there be?

How to use the Fundamental Counting Principle: In the United States, radio and television stations use call letters that start with K or W. How many different call letters with 4 letters are possible?

Homework: From pages , complete #1-24(even).

Permutations & Combinations What’s the difference? A permutation is an arrangement or listing in which order is important. A combination is an arragement or listing where order is not important.

Permutations… P(a,b) -or- a P b The number to start with…How many factors to use… EX: An ice cream shop has 31 flavors. Carlos wants to buy a three-scope cone with three different flavors. How many cones can he buy if order is important?

Homework: From page 386, complete #12-26 (even).

Let’s do an activity… You will be split into groups of 6. Each member of the group should shake hands with every other member of the group. As a group, make a list of each handshake. Answer the following questions: 1. How many different handshakes did you record? 2. Find the P(6,2) 3. Is the number of handshakes equal to P(6,2)? Explain…

Combinations… C(a,b) –or- a C b = P(a,b) b! EX: Four points are located on a circle. How many line segments can be drawn with these points as endpoints?

Homework: From page 390, complete #12-26 (even).
