SYNTHESIS DIRECTIONS: Construct the probability distribution for the random variables described in each of the following situation given below. 1. Five computers will be delivered to a certain school for testing, but three of them are defective. The principal will get two of these computers for his office. Let T represent the random variable representing the defective computers will occur. Find the values of random variable T. Possible Outcomes | Values of the Random Variable Y

Let we draw 3 computers at random from a lot of 7 computers of which 2 are defective. i. Draw a sample space for defective computer of this experiment if the computers are drawn with replacement and assign probabilities to each outcome. Also find the probability of at least two defective computers that can be chosen. ii. Draw a sample space of this experiment for defectives if the computers are drawn without replacement and assign probabilities to each outcome. Also find the probability of at least two defective computers that can be chosen

1. Four coins are tossed. Let Z be the random variable representing the number of heads that occur. Find the values of the random variable Z. Possible Outcomes | Value of the Random Variable Z 2. A shipment of five computers contains two that are slightly defective. If a retailer receives three of these computers at random, list the elements of the sample space S using the letters D and N for defective and non-defective computers, respectively. To each sample point assign a value x of the random variable X representing the number of computers purchased by the retailer which are slightly defective. Possible Outcomes | Value of the Random Variable X 3. Let T be a random variable giving the number of heads plus the number of tails in three tosses of a coin. List the elements of the sample space S for the three tosses of the coin and assign a value to each sample point. Possible Outcomes | Value of the Random Variable T
