Pollution of the rivers in the United States has been a problem for many years. Consider the following events: A: the river is polluted, B: a sample of water tested detects pollution, C: fishing is permitted. Assume P(A): 0.3, P(BIA)-0.75, P(B | A)0.20, P(C |An B) 0.20, P(C | A, n B)-0.15. P(C | An B')-0.80. (a) Find P(AnBnC). (b) Find P(B'nC). (c) Find the probability that the river is polluted, given that fishing is permitted and the sample tested...

7. Let C represent the event that a person has cancer. Let D represent the event that a person is diagnosed with cancer. In a certain region of the country it is known from pasit experience that the probability of selecting an adult over 40 years of age with cancer is 0.08. The probability of a doctor correctly diagnosing a person with cancer as having the disease is P(D C) 0.84, and the probability of incorrectly diagnosing a person without...

Have to show work for every problem 4. A company uses three plants to produce a new computer chip. Plant A produces 30% of the chips. Plant B produces 45% of the chips. The rest of the chips are produced by plant C. Each plant has its own defectiv rate. These are: plant A produces 3% defective chips, plant B produces 1% defective chips, plant C produces 5% defective chips. Hint: draw a tree diagram. (a) Construct a tree diagram...
