If x, the time (in minutes) to complete an change job at certain auto service station, is uniformly distributed over the interval 20 to 30, inclusively (20 ≤ x ≤ 30), then the probability that an oil change job is completed in less than or equal to 22 minutes, i. e., p(x ≤ 22) is

but which class are u may know that first
