5. Answer may be overstated, or suited to what the person thinks the interviewer wants

6.1 What is the difference between the probability distribution of a discrete

random variable and that of a continuous random variable? Explain.

A continuous random variable is achieved from information that can be measured

instead of counted. A continuous random variable is a variable that can assume an infinite

amount of possible values. The probability distribution of a discrete random variable

included values that a random variable can assume and the corresponding

probabilities of the values. The probability distribution of a continuous random variable has

two characteristics:

1. The probability that x assumes a value in any interval lies in the range 0 to 1.

2. The probability of all the (mutually exclusive) intervals within which x can assume a

value is 1.

A continuous probability distribution differs from a discrete probability distribution in

several ways:

1. The probability that a continuous random variable will...
