An article suggests the uniform distribution on the interval from 7.5 to 20 as a model for x = depth (in centimeters) of the bioturbation layer in sediment for a certain region.(d) What is the probability that x is between 11 and 17? P(11 ≤ x ≤ 17) = (e) What is the probability that x is between 12 and 18? P(12 ≤ x ≤ 18) = .
