A 10% chance of snow is a low probability.  That means it probably won't snow. Probability for Beginners: Solving Math Problems Intro to theoretical probability 56-57 What is probability?

Problem Solving      Concept/Skill Sample YouTube Learn Zillion Khan Academy Math Sense 3 PreGED Mathematics GED Mathematics Probability of One Thing Happening: Simple Probability If there are 27 books on the shelf, what is the probability you'll randomly grab a book with a blue cover if there are 6 books with blue covers?  Answer: 6 out of 27 or 6 / 27 reduces to 2 / 9 which is about 22%. Probability-Part One: Simple Probability Calculating the probability of an event by creating a ratio Simple Probability: Yellow Marble 64-65 214--217 186-187 Simple Probability: non-blue marble (NOTE: Stop video at 4.53) Probability of Multiple Things Happening Together: Compound Probability If a dice is rolled and a coin is flipped, what is the probability of getting a 6 on the dice and the coin landing on heads? The probability of getting a 6 is 1/6; the probability of getting a heads is 1/2. The probability of both is 1/6 x 1/2 = 1/12. The probability of both events happening is 1/12 or 8.33%. Probability-Part Two: Compound Probability Independent and Dependent Probability 66-67 218-219 188-189 Die rolling probability Probability with counting outcomes Compound probability of an independent event Die rolling probability with independent events Dependent probability introduction Dependent Probability Predicting with Probability If a salesperson makes a sale on 24% of her calls, how many sales should she expect to make if she plans to make 30 calls today?  Answer: About 7 (30 x .24 = 7.2) Making predictions with probability 68-69 Probability models example: frozen yogurt Concept/Skill Sample YouTube Learn Zillion Khan Academy Math Sense 3 PreGED Mathematics GED Mathematics      Problem Solving Post-Test 1.  In the Math Sense 3 book, complete pages 72-73.  Do NOT do problems 1, 2, 4 or 8.  It is OK to use a calculator for this test. 2.  Answers can be found on pages 171-172. 3.  A passing score is 8 out of 10.
