A discrete random variable is a variable that can only take some selected values. The values that it can take may be infinite in number (eg the counting numbers), but unlike a continuous random variable, it cannot take any value in between valid results.

What is discrete probability distribution?
It is a function that gives the probabilities associated with the discrete number of values that a random variable can take.

Can the Poisson distribution be a continuous random variable or a discrete random variable?
True
A random variable that can assume only a finite number of values is referred to as?
That would be a discrete variable; or, in your case, it would probably be called a discrete random variable.
Is the expected value of a discrete random variable equal to the mean of the random variable?
yes?
Is the number of pills in a container of vitamins discrete or continuous?
Discrete random variable
Is the random variable x equals 1 be stated that the random variable is discrete?
If x = 1 then X is not really a random variable but a constant.
Is the number of statistics students now reading a book discrete or continuous?
The random variable is discrete
What is the difference between a discrete and continuous random variable?
· A variable whose values are determined by the outcomes of a random experiment is called a random variable. A random variable is a discrete random variable if it can assume values, which are finite or countable infinite. For example, tossing of a die is a random experiment and its outcomes 1, 2, 3, 4, 5 and 6 are discrete random variable. When a coin is tossed, its outcomes head and tail are discrete random variable. Three coins are thrown; the number of heads is example of discrete random variable. Note that the outcomes need ot be integers or even numbers (eg colour of eyes). · If a random variable can assume every possible value in an interval [a, b], a< b, where a and b may be - infinity and + infinity respectively, for example, the points on number line between 0 and 1; Value of 'x' between 0 and 2; Number of heads on a coin when it is tossed infinite times.
The mean or expected value of the distribution of a discrete random variable is?
30.47
What is discrete probability distribution?
It is a function that gives the probabilities associated with the discrete number of values that a random variable can take.
What is the difference between discrete and cumulative distributions?
A discrete distribution is one in which the random variable can take only a limited number of values. A cumulative distribution, which can be discrete of continuous, is the sum (if discrete) or integral (if continuous) of the probabilities of all events for which the random variable is less than or equal to the given value.
