A site consists of 60% sand and 40% silt in separate layers and pockets. At this site, 10% of sand samples and 5% of silt samples are contaminated with trace amounts of arsenic. If a soil sample is selected at random, what is the probability that it is a contaminated sample? Also, if a soil sample was contaminated, what is the probability that the soil type is silt?
