The lengths of a runner's workout have a continuous uniform distribution between 49.29 min and 55.55 min. If one such workout is randomly selected, find P49 P49 = (Report answer accurate to 4 decimal places when needed.) A professor must spend different amounts of time with each student to help with various topics during office hours. These times follow an exponential distribution with the average amount of time = 21 minutes. of a) Find m m = b) Using your answer from part a), write the probability density function. f(x) = The average number of radioactive particles passing through a counter during 1 millisecond in a lab experiment is 13. Find the probability that more than 4 milliseconds pass between particles.
