Can a random variable be complex?
Section 5.10 Complex Random Variables
A complex random variable is defined by Z = AejΘ, where A and Θ are independent and Θ is uniformly distributed over (0, 2π). Find E[Z].
What are examples of random variables?
A typical example of a random variable is the outcome of a coin toss. Consider a probability distribution in which the outcomes of a random event are not equally likely to happen. If the random variable Y is the number of heads we get from tossing two coins, then Y could be 0, 1, or 2.
Which is an example of a continuous random variable?
Continuous random variables are usually measurements. Examples include height, weight, the amount of sugar in an orange, the time required to run a mile. A continuous random variable is not defined at specific values.
What are the 3 example of discrete random variable?
It is often the case that a number is naturally associated to the outcome of a random experiment: the number of boys in a three-child family, the number of defective light bulbs in a case of 100 bulbs, the length of time until the next customer arrives at the drive-through window at a bank.
