Using the following uniform density curve, answer the question. A graph has a horizontal x-axis labeled from 0 to 8 in increments of 1 and vertical scale labeled "P(x)" labeled from 0 to 0.125 in increments of 0.125. The plotted curve consists of two line segments: a horizontal line segment from (0, 0.125) to (8, 0.125) and a vertical line segment from (8, 0.125) to (8, 0). What is the probability that the random variable has a value between 1.1...
