Exercise 3
In the graph that appears in figure 7 the probabilities of (Cognitive) with the different variables, like age, activities and Depression are shown. That is, what is the probability that a person has Cognitive Impairment if he is older than 65 years, performs activities such as (physical, reading, crafts, learning new things) and has depression.
For our exercise using the Bayesian methodology in Figure 8, it shows how the nodes represented and their specifications would be, since this 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

P(C)
= 0.69

P
(D|A, B) = 0.66
