Let x be the amount of time (in minutes) that a particular San Francisco commuter must wait for a train. Suppose that the density curve is as pictured below (a uniform distribution). A horizontal line segment is graphed on the coordinate plane. The horizontal x axis is labeled "Time (minutes)" and has two tick marks at 0 and 20. The vertical axis is labeled "Density" and has one tick mark at 0.05. The line starts at the coordinate (0, 0.05), and stops at the coordinate (20, 0.05). (a) What is the probability that x is less than 7 min
