Thursday Nov. 10, 2011 • You will need: • Math book • Folder/notebook • Calculator • Bell Ringer • A. What is the probability of rolling an odd number on a six sided dice? • B. What are the odds of rolling an odd number on a six sided dice?
Friday Nov. 11, 2011 • You will need: • Math book • Folder/Notes • Calculator • Bell Ringer • A. Show the sample space for the probability of flipping a coin three times. • What is the probability of tossing a at least two heads?
Monday, Nov. 14, 2011 • You will need: • Math book • Folder/notebook • Bell Ringer: • A. What is theoretical probability and experimental probability? (pg. 211) • B. What is a baseball players batting average if they hit 20 out of every 60 balls that are pitched at them?
Lesson 32 Probability
Probability • The likelihood that a particular event will occur. • To represent the probability of event A we use the notation P(A)
Range of Probability • The Range of Probability is a ratio of favorable outcomes to possible outcomes. It is expressed as a number ranging from zero to one. • Remember that a ratio is a comparison of two numbers by division. • Look on pg. 210
P(Event)= number of favorable outcomes number of possible outcomes
Example 1 • The spinner show is spun once. What is the probability the spinner will stop • In sector A? • In sector A or B? • In sector A, B, C, or D?
Odds • Is the ratio of the number of favorable to unfavorable outcomes. Expressed with a colon (:) • Favorable : Unfavorable
Examples • What are the odds you will roll a 5 on a six sided dice? • What are the odds you will flip a heads on a coin?
Compliment • If we know the probability of an event, we can find the probability of its complement by subtracting the probability from 1.
Examples • What is the compliment of a .25 probability? • What is the compliment probability of an even that has a 50% chance of happening?
Sample Space • Collection of possible outcomes • pg. 212-213
Example • Nathan flips a coin three times. • Predict: which is more likely, that he will get heads at least once or that he will not get heads at least once. • Find the probability of getting heads at least once. • Find the probability of not getting heads at least once.
Theoretical Probability • Found by analyzing a situation • Coin tossing • Dice rolling
Experimental Probability • Determined statistically • Baseball statistics • Free throw shots
