1. PROBABILITY, EVENTS AND OUTCOMES Yo yo yo welcome back!!!!!!!! Happy NEW YEAR! SWBAT: Define probability, event & outcomes Determine the probability of a “favorable” even occurring

2. Ex: …. In the problem above, the experiment is spinning the spinner. Do you agree?! An experiment is a situation involving chance or probability that leads to results called outcomes.

3. The possible outcomes are landing on orange, blue, green or red. An outcome is the result of a single trial of an experiment.

4. One event of this experiment is landing on blue. An event is one or more outcomes of an experiment.

5. The probability of landing on blue is one-fourth. Probability is the measure of how likely an event is.

6. To land on BLUE would be a “favorable” outcome for me. Blue blue blue is my favorite color (presently).

7. Yes, write this down too!!  Probability Of An Event P(A) =

8. What’s the probability of landing on yellow? Red? Probability is the measure of how likely an event is.

9. Imagine…  A glass jar contains 6 red, 5 green, 8 blue and 3 yellow marbles. If a single marble is chosen at random from the jar, what is the probability of choosing a red marble? a green marble? a blue marble? a yellow marble?  What are the possible outcomes?....

10.  A glass jar contains 6 red, 5 green, 8 blue and 3 yellow marbles. If a single marble is chosen at random from the jar, what is the probability of choosing a red marble? a green marble? a blue marble? a yellow marble?

11.  P(red) =

12.  A glass jar contains 6 red, 5 green, 8 blue and 3 yellow marbles. If a single marble is chosen at random from the jar, what is the probability of choosing a red marble? a green marble? a blue marble? a yellow marble?  P(green) =

13.  A glass jar contains 6 red, 5 green, 8 blue and 3 yellow marbles. If a single marble is chosen at random from the jar, what is the probability of choosing a red marble? a green marble? a blue marble? a yellow marble?  P(blue) =

Which of the following is an outcome? a.Rolling a pair of dicec. Choosing two marbles from a jar b.Landing on red  3. Which of the following experiments does NOT have equally likely outcomes? a.Choose a # at random from 1-7 c. Choose a letter at random from the word SCHOOL b.Toss a coin d. None of these  4. What is the probability of choosing a vowel from the alphabet?  5. A number from 1 - 11 is chosen at random. What is the probability of choosing an odd number?
