Module 4 : Probability

In lesson 4.01, what did you learned about Sample Space? -Definition -Example of Sample Space

Lesson 4.01- Sample Space-

If you randomly select a letter from the word g i g g l i n g Lisa stated the sample space would be {g i l n} Is she correct? Yes or No Explain your reasoning.

If you randomly select a letter from the word A S S E S S M E N T Hunter stated the sample space would be {A S E M N T} Is he correct? Explain.

Key Points of Sample Space

Sample Space may be written in different ways: List Set Notation Abbreviated If there is more than one of the same outcome, all events must be listed separately.

Lesson 4.03- Likelihood f Events Remember, the probability of any event, must fall within the range of ______ to _____ .

Organize these events into the correct categories.

1. Rolling a 7 on a standard dice label 1 -6
2. 9/10 chance of rain tomorrow
3. 1/5 chance of rain on tomorrow
4. Picking a green marble for a jar that contain 8 green marbles

You have 10 golf balls: 2 red - 3 blue - 5 green What is the probability that you will pick a BLUE golf ball? Write the probability as a fraction, decimal, and percent.

What is the probability of choosing a yellow golf ball? Is this considered certain, likely, unlikely or impossible? Why?

If you flip a coin 30 times and get the following results: heads: 18 tails: 12 What is the experimental probability for the coin landing on tails? How do the theoretical and experimental probabilities compare?

If you flip a coin 50 times and get the following results: heads: 22 tails: 28 What is the experimental probability for the coin landing on tails as a fraction, decimal and percent? How do the theoretical and experimental probabilities compare?

An experimental was conducted with 50 trials and the data is given below.

Calculate the experimental probability for selecting the color yellow. How do the theoretical probability and experimental probability compare?

1. What is the probability that you will pick a red golf ball? Write the probability as a fraction, decimal, and percent. Is this theoretical probability or experimental probability?
2. If you performed an experimental, what it is experimental probability that you would pick a red golf ball if you picked 10 golf balls from the box and had red, 2 green, and 4 blue?
3. If I told you that I will pick a yellow golf ball from the box, what type of event is that? (impossible, unlikely, likely, certain)
4. Create a sample space for organizing the boxes on the shelves by color.

Awesome job Luke! Today you were able to discuss the following during your DBA:

• You have 5 green, 2 red and 3 blue folders. If you are asked to select a yellow folder, what type of event is that? Certain, likely, unlikely or impossible?
• If you have 2 purple, 2 red, 3 green and 3 blue golf balls, what is the probability of choosing a red golf ball?
• You discussed the difference between experimental and theoretical probability.
• You have a bag filled with crayons. You have 2 blue, 3 red, 4 green and 1 yellow. What is the sample space for choosing 1 crayon from the bag?
