1. GOOD MORNING CLASS!! HOW ARE YOU?

2. GUESS THE WORD!!

3. S A S S T T C STATISTICS GUESS THE WORD!!

4. PROBABILITY P R B T B I Y GUESS THE WORD!!

5. RANDOM VARIABLE R M D B R A E A GUESS THE WORD!!

6. D S E C T DISCRETE GUESS THE WORD!!

7. CONTINUOUS C N N S T U U GUESS THE WORD!!

9. Probability Distribution of Discrete Random Variable

10. LEARNING OBJECTIVES: At the end of the lesson, the learners should be able to; illustrate a probability distribution for a discrete random variable; find the possible values of a random variable; and appreciate the importance of probability distribution in real life.

11. The purpose of using random variable is so that we could measure observations and process data to make a conclusion about the population.

12. POSSIBLE OUTCOMES VALUE OF RANDOM VARIABLE X (number of eggplants with worm attacks) NNN NNW NWN NWW WNN WNW WWN WWW The possible values of the random variable X are 0, 1, 2, and 3. 1 1 2 1 2 2 3

13. LET’S TRY YOUR KNOWLEDGE!

14. “TWO HEADS ARE BETTER THAN ONE” Directions: Find your partner and help each other to finish the task. Suppose that 4 coins are tossed. Let Y be the random variable representing the number of heads that occur. Complete the table below and find the possible values of Y. POSSIBLE OUTCOMES VALUE OF RANDOM Y (number of heads) HHHH 4 HHHT 3 HHTH HHTT HTHH HTHT HTTH HTTT

15. THHH THHT THTH THTT TTHH TTHT TTTH TTTT

16. What is the purpose of using random variables?? Is it easy to find the possible values of random variable? How can you use this knowledge in your life?

17. ANSWER THIS! Directions : Read the situation and fill out the table below. Suppose that you roll 2 dice. Let X be the random variable representing the number of times that 5 dots will appear. List all the possible outcomes and find the possible values of random variable X. POSSIBLE OUTCOMES Value of random variable X (number of 5 dots) 1 & 1 1 & 2
