Is the variable is discrete or continuous the number of keys on each student's key chain?
A random variable such as the number of keys on each student's key chain is discrete because you can list the possible values it can assume. If it was continuous one would not be list a continuous random variable because it would be impossible. The keys on the key chains would be discrete.
Is the number of pills in a container of vitamins discrete or continuous?
Discrete random variable
Does the probability that a continuous random variable take a specific value depend on the probability density function?
No. The probability that a continuous random variable takes a specific value is always zero.
Is the exact time it takes to evaluate 27 72 discrete or continuous?
it is a continuous random variable
Is the normal probability distribution applied to a continuous random variable?
Yes.
Is the gender of college students a discrete random variable a continuous random variable or not a random variable?
It is a discrete random variable.
Can the Poisson distribution be a continuous random variable or a discrete random variable?
True
Is temperature an example of continuous variable?
Yes. It is a continuous variable. As used in probability theory, it is an example of a continuous random variable.

Is the number of pills in a container of vitamins discrete or continuous?
Discrete random variable
Is the number of statistics students now reading a book discrete or continuous?
The random variable is discrete
Random variable that can take any numeric value within a range of values?
continuous random variable
Define continuous random evevt?
Usually we consider a random variable which assigns a value to the outcome of an event. The value assigned to the outcome can be either discrete or continuous. The continuous random variable is a random variable whose domain is defined over a continuous range. Examples: Daily inches of rain, speed of cars on highway, purchases made everyday at grocery stores.
What is meant by discrete random variable?
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.
Does the probability that a continuous random variable take a specific value depend on the probability density function?
No. The probability that a continuous random variable takes a specific value is always zero.
Is the exact time it takes to evaluate 27 72 discrete or continuous?

Is the normal probability distribution applied to a continuous random variable?
Yes.
