Exercise 2 Bayesian Probability.

Exercise 2 In the graph that appears in figure 5, the probabilities of (Depression) are shown with the different variables, such as age and activities.

That is, what is the probability that a person has depression if he is older than 65 years and performs activities such as (physical, reading, crafts, learning new things).

For our exercise using the Bayesian methodology in Figure 6, it shows how the nodes represented and their specifications would be, since it is the part that interests us.

P(A) = 0.78	P (C|A, B) = 0.65	P (C|A, ¬B) = 0.86
P(B) = 0.70	P (C|¬A, B) = 0.57	P (C|¬A, ¬B) = 0.75
