Define (a) random process, (b) random variable, (c) discrete random variable, and (d)
(a)
Define the term “random process”.
Explanation of Solution
Random process:
The random process is defined as the probability model which is assigned to the corresponding outcomes that exist in the sample space.
(b)
Define the term “random variable”.
Explanation of Solution
Random variable:
The random variable is defined as the rule or function that assigns numerical values to all outcomes which exist in the sample space of a random experiment.
(c)
Define the term “discrete random variable”.
Explanation of Solution
Discrete random variable:
The discrete random variable is a random variable which has the countable number of distinct values.
(d)
Define the term “Probability distribution”.
Explanation of Solution
Probability Distribution:
The probability distribution assigns probabilities corresponding to the values of random variable.
