Lesson 0­9 thru 0­12.notebook August 23, 2012
L0­9 & L0­10 Remember...
Volume...
*Volume of a rectangular prism = l x w x h
*Volume of a cylinder = r h
2
*Surface Area = the sum of areas of all the faces
**For a rectangular prism:2lw + 2lh + 2wh
**For a cylinder: 2 rh + 2 r

6. Lesson 0­9 thru 0­12.notebook August 23, 2012
L0­11 & L0­12:
Remember...
*probability ­ favorable outcomes
total outcomes
*sample space ­ a list of all the possible outcomes
FYI...when the probability is 0 ­ the event is impossible to occur...
when the probability is 1 ­ the event is certain to occur
*complements ­ the events for and the events for NOT
i.e. ­ P(rolling a 1) and P(not rolling a 1)
FYI...the sum of the probabilities of any 2 complementary events is always 1

7. Lesson 0­9 thru 0­12.notebook August 23, 2012
*tree diagram ­ one method used to list out all the possible outcomes of an event
*Fundamental Counting Principle ­ the number of outcomes is related to the number of choices
i.e. ­ if there are 4 possible sizes for fish tanks and 3 possible shapes,
then there are 4 x 3 or 12 possible fish tanks (outcomes)
*odds ­ favorable outcomes
unfavorable outcomes

8. Lesson 0­9 thru 0­12.notebook August 23, 2012
Examples (L0­11):
A) Find the probability of rolling an even number (on one die).
P(even) = 3/6 = 1/2
B) Find the probability of rolling a number less than 5 (on one die).
P(number less than 5) = 4/6 = 2/3
C) The spinner is spun and a die is tossed. Use a tree diagram to find the sample space. State
the number of outcomes.
A B
C D

MEASURES OF CENTRAL TENDENCY:
*mean ­ average
*median ­ middle (when put in order)
*mode ­ most often
MEASURES OF VARIATION:
*range ­ highest minus lowest

*quartiles ­ separates the data into 4 equal subsets (Q1, Q2, Q3)
*Q1 (lower quartile) ­ median of the lower half
*Q2 ­ median
*Q3 (upper quartile) ­ median of the upper half
