Lesson 1 Extra Practice Probability Of Simple Events Answer Key

Scenario: A bag contains 4 red, 6 blue, and 2 green marbles. Total marbles = 12. Favorable outcomes: 4 Answer: 4/12, which simplifies to 1/3 Find P(blue or green): Favorable outcomes: 6 + 2 = 8 Answer: 8/12, which simplifies to 2/3 Find P(yellow): Favorable outcomes: 0 (there are no yellow marbles) Answer: 0 Section 3: Spinning a Spinner

[ P(\textevent) = \frac\textNumber of favorable outcomes\textTotal number of possible outcomes ] Scenario: A bag contains 4 red, 6 blue, and 2 green marbles
