During certain time periods at a​ hospital, patients arriving at the emergency room have waiting times that are uniformly distributed between 0 and 5 minutes. Assume that a patient is randomly​ selected, and find the probability that the waiting time is greater than 1.25 minutes.

The number of automobile sold weekly at a certain dealership is a random variable with expected value 16.Give an upper bound to the probability that the next week sales exceed 18.

There is a bus coming to a bus stop every 10 minutes. The waiting time of any person at the stop is a random variable with a continuous uniform distribution. What is the probability that the waiting time is at most two minutes?

A survey showed that 79​% of adults need correction​ (eyeglasses, contacts,​ surgery, etc.) for their eyesight. If 15 adults are randomly​ selected, find the probability that at least 14 of them need correction for their eyesight. Is 14 a significantly high number of adults requiring eyesight​ correction? The probability that at least 14 of the 15 adults require eyesight correction is nothing. ​(Round to three decimal places as​ needed.)

Cal Poly Pomona found that 15% of its students withdraw without completing Calculus I course. Assume that 30 students registered for the course. Compute the probability that exactly 6 students will withdraw. Leave your answer in four decimal places.
