|x| - 2|x - 3| = \begin{cases} x - 6, & \text{if } x < 0 \\3x - 6, & \text{if } 0 \leq x < 3 \\-x + 6, & \text{if } x \geq 3 \end{cases}

1. For \(x < 0\):
|x| = -x \quad \text{and} \quad |x - 3| = -x + 3
-x - 2(-x + 3) = x - 6

2. For \(0 \leq x < 3\):
|x| = x \quad \text{and} \quad |x - 3| = -x + 3
x - 2(-x + 3) = 3x - 6

3. For \(x \geq 3\):
|x| = x \quad \text{and} \quad |x - 3| = x - 3
x - 2(x - 3) = -x + 6

A particular employee arrives at work sometime between 8:00 a.m. and 8:50 a.m. Based on past experience the company has determined that the employee is equally likely to arrive at any time between 8:00 a.m. and 8:50 a.m. Find the probability that the employee will arrive between 8:05 a.m. and 8:40 a.m. Round your answer to four decimal places, if necessary.
