Samples of emissions from three suppliers are classified for conformance to air-quality specifications. The results from 135 samples are summarized as follows: Let A denote the event that a sample is from supplier 1, and let B denote the event that a sample conforms to specifications. If a sample is selected at random, determine the following Probabilities: P(A)=?(4points)P(B)=?(4points) 3 P(A)=?(4points)P(AB)=?(5points)P(AB)=?(5points)
