Question 5 of 15 0/1 View Policies Show Attempt History Current Attempt in Progress X Incorrect. What is the difference between the probability distribution of a discrete random variable and that of a continuous random variable? Select each correct answer. A discrete random variable has countable values, a continuous random variable has values that are not countable. A continuous random variable has countable values, a discrete random variable has values that are not countable. The probability that a continuous random variable x assumes a value within a certain interval is given by the area under the curve between the two limits of the interval. For a discrete random variable the value is given by the summation of values between those two points. The probability distribution of a continuous random variable assigns probabilities to points while that of a discrete random variable assigns probabilities to intervals. The probability distribution of a discrete random variable assigns…
