Suppose the reaction temperature x (in °c) in a certain chemical process has a uniform distribution with a = −6 and b = 6. (a) compute p(x < 0). (b) compute p(−3 < x < 3). (c) compute p(−4 ≤ x ≤ 5). (round your answer to two decimal places.) (d) for k satisfying −6 < k < k + 4 < 6, compute p(k < x < k + 4). (round your answer to two decimal places.)
