- Let X be a continuous random variable with range [−ln5,0] and its probability density function is given by the following function: f(x)=ce^−x, where cc is a constant. (1) Find the value of c . Answer: (2) Find the probability P(−ln2≤X≤0) . Answer:arrow_forwardFind a value of k that will make f a probability density function on the indicated interval. ƒ(x) = kx5; [0, 6]arrow_forwardfind the value of the constant c so that the given function is a probability density function for a random variable over the specified interval. . ƒ(x) = 1/ 6 x over [3, c].arrow_forward
- A continuous random variable has a density function f(x)= 2(5-x)/5 , where 2<x<3. Calculatethe following probability correct up to 3 decimal places, and make the graph for part (a) only in Answer sheet:P (x < 2.5)P (x > 2.2)P (2.1 ≤arrow_forwardThe distance x, in feet, between successive cars on a certain stretch of highway has the following probability density function, where k=1/a and a is the average distance, in feet, between successive cars over some period of time. f(x)= ke^-kx, for 0 ≤ x < ∞ A transportation planner determines that the average distance between cars on a certain highway is 60 ft. What is the probability that the distance between two successive cars, chosen at random, is 20ft or less? P(0 ≤ x ≤ 20) =arrow_forwardGiven the distribution function of monthly income (in thousands) of a personal shopper,X is:a) Find the probability density function of X .b) Find the probability that the income gained is: i) at most RM5,000,ii) between RM4,500 and RM6,000.arrow_forward
- In a study of intelligence, the time (in seconds) for a laboratory animal to reach a reward in a maze was found to have a probability density function f(t) = 8 t 2 , t ≥ 8 where 8 seconds is the minimum time to traverse the maze. (a) Find the probability that an animal chosen at random takes between 28 and 56 seconds. (b) Find the probability that an animal chosen at random takes more than 28 seconds given that it took less than 56 seconds.arrow_forwardFind a value of k that will make f a probability density function on the indicated interval.ƒ(x) = kx2; [0, 5]arrow_forward
