Awater well is to be drilled in the desert where the soil is either rock, clay or sand. the probability of rock p(r)equals=0.53. the clay probability is p(c)equals=0.21. the sand probability is p(s)equals=0.26. if the soil is rock, a geological test gives a positive result with 35% accuracy. if it is clay, this test gives a positive result with 48% accuracy. the test gives a 75% accuracy for sand.
given the test is positive, what is the probability that the soil is clay, p(clay | positive)? use bayes' rule to find the indicated probability.
