  1. 20% no; only 1 out of 5 is yellow. Since 1 out of 10 would be yellow, the chances would be less likely. Her chances increase to 50%

  2. Probability can NOT be greater than 100% P(event) = # of favorable outcomes # of possible outcomes

  3. Probability: the chance that some event will occur.

  6. The probability of an event is a ratio that compares the number of favorable outcomes to the number of possible outcomes. number of favorable outcomes P (event) = number of possible outcomes

  7. If a number cube has six sides labeled 1 through 6. There are six possible outcomes if the cube is rolled. Find the probability of rolling a 6. number of favorable outcomes P(6) = number of possible outcomes 1 P(6) = 6

  8. Find the probability of rolling a 2, 3, or 4. 3 P(2,3, or 4) = 6 Simplify 1 2

  9. What is the probability of landing on yellow? P(yellow) =

  10. Complementary events: two events in which either one or the other must happen, but they cannot happen at the same time

  11. Find the probability of NOT landing on yellow. These two events are complements. P(yellow)=1/9 P(not yellow)=

  12. A letter tile is randomly chosen. Find each probability.

  13. P(k) =

  14. P(a) =

  15. P(not l) =

  16. P(dog) =

  17. P(dog or cat) =

  18. Represents the probability of an event taking place If Morgan chose a yellow carnation. The probability of blue eyes plus the probability of not blue eyes = 100%. They're complementary events. P(purple rose) =
