Which of the following is true about the probability density function (pdf) of a continuous randomvariable?O The area underneath it must be positive and strictly less than oneO cdfy)-cdffx) represents the probability the random variable is less than y but greater than or equal to x. Youmay 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 probabilitiesO It can never be higher than one, because probabilities are never higher than one
