A. A machine is set to pump cleanser into a process at the rate of 12 gallons per minute. upon inspection, it is learned that the machine actually pumps cleanser at a rate described by the uniform distribution over the interval 9 to 15 gallons per minute. B. find the probability that between 11 gallons and 13 gallons are pumped during a randomly selected minute.

C. suppose a uniform random variable can be used to describe the outcome of an experiment with the outcomes ranging from 30 to 60.

D. what is the probability that this experiment results in an outcome less than 45?
