Determine whether or not the distribution is a discrete probability distribution and select the reason why or why not.

x −4 −3 −2
P(X=x) 0.55 0.39 0.06

Answer

First, decide whether the distribution is a discrete probability distribution, then select the reason for making this decision.

Decide Yes No

Reason Since the probabilities lie inclusively between 0 and 1 and the sum of the probabilities is equal to 1. Since at least one of the probability values is greater than 1 or less than 0. Since the sum of the probabilities is not equal to 1. Since the sum of the probabilities is equal to 1. Since the probabilities lie inclusively between 0 and 1.

Solutions

Expert Solution

The given probability distribution is discrete probability distribution because variable X takes finite values and given probabilities of values of X lies between 0 and 1 both inclusive and sum of probabilities is equal to 1

Discrete R.V and Probability Distribution
A new battery's voltage may be acceptable (A) or unacceptable (U). A certain ash-light requires two batteries, so batteries will be independently selected and tested until two acceptable ones have been found. Suppose that 90% of all batteries have acceptable voltages. Let Y denote the number of batteries that must be tested. (a) What is p(2), that is, P(Y = 2)? (b) What is p(3)? [Hint: There are two different outcomes that result in Y = 3.] (c) To have...

An electronics store has received a shipment of 20 table radios that have connections for an iPod or iPhone. Twelve of these have two slots (so they can accommodate both devices), and the other eight have a single slot. Suppose that six of the 20 radios are randomly selected to be stored under a shelf where the radios are displayed, and the remaining ones are placed in a storeroom. Let X= the number among the radios stored under the display...

In an assembly-line production of industrial robots, gearbox assemblies can be installed in one minute each if holes have been properly drilled in the boxes and in ten minutes if the holes must be redrilled. Twenty gearboxes are in stock, 2 with improperly drilled holes. Five gearboxes must be selected from the 20 that are available for installationcin the next five robots. (a) Find the probability that all 5 gearboxes will fit properly. (b) Find the mean, variance, and standard...

A manufacturing company uses an acceptance scheme on items from a production line before they are shipped. The plan is a two-stage one. Boxes of 25 items are readied for shipment, and a sample of 3 items is tested for defectives. If any defectives are found, the entire box is sent back for 100% screening. If no defectives are found, the box is shipped. (a) What is the probability that a box containing 3 defectives will be shipped? (b) What...
