Which of the following is true about the probability density function (pdf) of a continuous random variable? O The area underneath it must be positive and strictly less than one O cdfy)-cdf(x) represents the probability the random variable is less than y but greater than or equal to x. You may assume y>x and cdf stands for the cumulative density function, O You have to be careful to note the =' part of any inequalities when working out probabilities O It can never be higher than one, because probabilities are never higher than one
