Question: Study the probability tree below: (A) Discuss the difference between P(M|U) and P(U|M), and between P(N|V) and P(V|N), in terms of a, b, c, d,

Study the probability tree below:

Start M N M c+d=1 a+b=1 e+f=1 a, b, c, d, e, f #0

(A) Discuss the difference between P(M|U) and P(U|M), and between P(N|V) and P(V|N), in terms of a, b, c, d, e, and f.

(B) Show that ac + ad + be + bf = 1. What is the significance of this result?

Start M N M c+d=1 a+b=1 e+f=1 a, b, c, d, e, f #0
