Warm Up: Solve in Math Journal • A bag holds 4 marbles: yellow, red, green, blue. • A box holds 3 marbles: purple, brown, white. • Draw a tree diagram to show all the possible outcomes of picking one marble from each container.
Probability 10/18
If you were to pick one without looking, what color are you most likely to get? • Red
It is equally likely you will pick green and what color? • Orange
Do you think you will pick yellow? • It is unlikely.
Can you be certain that you will choose purple? • No outcome is certain here.
What are the chances you will choose a white gumball? • It is impossible.
Probability: • The chance that an outcome will occur is its probability. The words certain, likely, equally likely, unlikely, and impossible can describe probability.
Use words to describe probability: • Marta has 8 marbles in the bag; 3 marbles are red, 3 marbles are blue, and 2 marbles are yellow. • Describe how likely it is that she will choose a yellow marble from the bag. In the bag, less than half of the marbles are yellow. So, it is unlikely that Marta will choose a yellow marble.
Use words to describe probability: • The table shows the coins Tucker has in his pocket. Suppose he drops a coin on the ground. Describe the probability that the coin he dropped is a dime. Of the 8 coins in Tucker’s pocket, 5 are dimes. So, it is likely that Tucker dropped a dime.
Use numbers to describe probability: • The letter tiles below spell out mathematics. Use numbers to describe the probability of choosing a vowel without looking. S A I T M E A C M T H Four our of eleven letters are vowels. So, the probability of choosing a vowel is 4 out of 11.
