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...
