Let $x$ be the amount of time (in minutes) that a particular San Francisco commuter must wait for a BART train. Suppose that the density curve is as pictured (a uniform distribution): a. What is the probability that $x$ is less than 10 minutes? more than 15 minutes?

Step 1
Since the distribution is uniform, the probability density function (pdf) is constant over the interval of possible waiting times. Let's denote the interval as $[a, b]$. Show more…

Let X be the waiting time for a train to pass by. Suppose X is exponentially distributed with an average value of 9 minutes. find the probability that the wait time is between 6 and 14 minutes

A train arrives at a station every 15 minutes. It is assumed that the waiting time for a particular individual is a random variable with a continuous uniform distribution. (a) What is the probability that the individual waits more than 10 minutes? (b) What is the probability that the individual waits between 6 and 12 minutes?
