Point out the wrong statement.

A random variable is a numerical outcome of an experiment
There are three types of random variable
Continuous random variable can take any value on the real line
None of the mentioned

The correct answer is: C. Continuous random variable can take any value on the real line.

A random variable is a numerical outcome of an experiment. There are two types of random variables: discrete and continuous. Discrete random variables can take on only a finite or countable number of values, while continuous random variables can take on any value in an interval.

For example, the number of heads that come up when flipping a coin is a discrete random variable, because it can only take on the values 0, 1, or 2. The height of a person is a continuous random variable, because it can take on any value between 0 and infinity.

The statement “Continuous random variable can take any value on the real line” is wrong because it does not take into account the fact that continuous random variables can only take on values within a certain interval.
