2.7.2) Two events A and B are mutually exclusive with P(A)

2.7.2) Two events A and B are mutually exclusive with P(A) = 0.3 and P(B) = 0.5. Are these two events A and B statistically independent? Determine P(AUB). 2.7.4) Samples of emissions from three suppliers are classified for conformance to air-quality specifications. The results from 100 samples are summarized as follows: Conforms Yes No 1 25 5 Supplier 22 8 3 30 10 Let A denote the event that a sample is from supplier 2 and B denote the event that a sample conforms to specifications. (a) Are events A and B independent? (b) Are events A and B mutually exclusive? (c) Determine P(A B)
