Probability & Probability Rule Lesson 2-8

Vocabulary Vocab WordDefinitionExample OutcomesThe number of results that might happen or can happen ProbabilityThe chance or likelihood that something will happen

Probability *always presented in fraction form # of desired outcomes -- # of what you want to happen # of total possible outcomes Total # of what can actually happen

Probability Using a die (or six sided-number cube): What is the probability (P) of rolling a 5? How many 5s on the die? How many sides on the die? Put the answer as a fraction… What is the probability (P) of rolling a 2? What is the (P) of rolling an even #? What is P(number less than 8)?

Probability Using a spinner or pie chart… What is the P(blue)? What is the P(not blue)? What is the P(pink)? What is the P(green or yellow)?
