A softer point of view is that Bayesian learning theory is a model for learning, and it has the merit of being a simple model that can be programmed on computers. Probability theory in general, and Bayesian learning theory in particular, are part of the core of artificial intelligence. 6 Independence Intuitively, we would say that two events, A and B, are independent if knowing that one had occurred gave us no information about whether the other had occurred; that is, P(A | B) = P(A) and P(B | A) = P(B).

To improve the chances of a correct diagnosis, the concentration of digitalis in the blood can be measured. Bellar et al. (1971) conducted a study of the relation of the concentration of digitalis in the blood to digitalis intoxication in 135 patients. Their results are simplified slightly in the following table, where this notation is used: T + = high blood concentration (positive test) T − = low blood concentration (negative test) D+ = toxicity (disease present) D− = no toxicity (disease absent) D+ D− Total T+ T− 25 18 14 78 39 96 Total 43 92 135 Thus, for example, 25 of the 135 patients had a high blood concentration of digitalis and suffered toxicity.

5. Thus, by merely asking the teacher a question, Drew will increase his probability of leaving from 13 to 12 . What do you think of this scheme? 59. A box has three coins. One has two heads, one has two tails, and the other is a fair coin with one head and one tail. A coin is chosen at random, is flipped, and comes up heads. a. What is the probability that the coin chosen is the two-headed coin? b. What is the probability that if it is thrown another time it will come up heads? c. Answer part (a) again, supposing that the coin is thrown a second time and comes up heads again.
