Question 3 15 points A model of a drug reaction describes an outcome A with probability P(A) = 0.4 and another outcome B with probability 0.3. Researchers have deduced that a conditional reaction, the outcome B after the outcome A, should occur with probability 0.4. a. Find the probability that both A and B occur. b. Use a Venn diagram to explain your calculation. Both the diagram and words are required. c. The researchers are interested in the event that B occurs but A does not. What is this probability
