Which of the following is not true about continuous random v

Which of the following is not true about continuous random variables? (Points : 5)        The entire area under each of the curves equals 1.
       Some may be described by uniform distributions or exponential distributions.
       They can only be integer values.
       The area under each of the curves represents probabilities.
       They have an infinite set of values.

Solution

ANSWER: They can only be integer values. [FALSE, they should take any value on a certain interval]
