Think about a density curve that consists of two straight-line segments. the first goes from the point (0, 1) to the point (0.7, 1) then the second goes from the point (0.7, 1) to the point (1.3, 0). a. sketch this density curve: b. what is the probability that x falls below 0.5? c. what is the probability that x lies between 0.7 and 1.3? d. what is the probability that x lies above 0.2? e. what i
