So if 50 is given to me Probability, density, function what I am It takes two drive to school. He is my Jordan minutes. So the probability that the it will take less than 15 minutes is be off. He lives in equal to 15. Here is an equal to zero. You see the entitled 0 15 and 50 You deep. What? Probably there it'll take more than often are often hours, 30 minutes. So probably be off key. Better than eagles hearty is the integral rt to infinity if you speak duty.
