Question 894311: A particular chemical analysis has a rather limited range. Typically, 15% of the samples are too concentrated to be assayed without dilution, and 20% are contaminated with an interfering material that must be removed before analysis. The rest may be analyzed without pretreatment. Assume that both too concentrated and contaminated never occur. What is the probability that a randomly selected sample can be assayed without pretreatment?
