5. Number of times the first card is face card and the second card is not a face cardTwo balls are picked in succession without replacement 4 white balls and. 5 green balls. Let Y be the random variable representing the number of green balls. Find the values of the random Variable Y. Complete the table belOW- . ' - ' .. _ ~ . Value of Random Variable Y , Possible Outcomes ' " (number 01' green balls) Four coins are toss. Let Y be the random variable representing the number of tails that occur. Find the values of the random variable Y. Value of Random Variable Y Possible Outcomes (number of tails)Give your answer in the following statements. 1. A is a set of possible values from a random experiment. For example, in tossing a coin, we can either get head or tail, such tossing a coin is an experiment where we can give values for such event. 2. A is one that may take on only a countable number of distinct values such as 0,1,2,3,4, etc. This variable is usually (but not necessarily) counts. It is a random variable that can take only a finite number of distinct values. 3. To find the values of a random variable, we have to follow these steps: first, list all in sample space; second, find the for each simple event; third, list the possible values for a random variable X and identify the value for each simple event and finally; find all simple events for which X = k, for each possible value k.The households of a local community were surveyed about the number of occupants who are working.

Thus, to each outcome in the sample space we shall assign a value. These are 0, 1, 2, or 3. If there is no defective laptop, we assign the number O; if there is 1 non-defective laptop, we assign the number 1; if there are two non- defective laptops, we assign the number 2 and 3, if there are three non- defective laptops. The number of non-defective laptops is a random variable. Let D represents the defective laptop and N represents the non-defective laptop. If we let X be the random variable representing the number of non-defective laptops, show the values of the random variable X. Complete the table below to show the values of the random variable. Value of the Random Variable X Possible Outcomes (number of non-defective laptops) This time, you need to reflect on the following questions because it will help you to understand the appropriate way in finding the possible values of a random variable. Answer the following questions: 1. How do you find the activity? 2. Were you able to complete the table? If yes, how? If no, why? 3. Will you be able to find the values of a random variable? If yes, how? If no, why? 4. In your own words, how will you describe a random variable? 5. How do you find the possible values of a random variable?Understanding Possible Values of Random Variables. Answer the following questions. 1. How do you find the values of a random variable? 2. How is this variable, as described in Algebra, similar to a random variable? How do they differ
